As a result, the length of time required to earn the doctorate has emerged as one of the major issues in graduate education. The time issue Is viewed not so much as one involving the expected or actually enrolled period of time required for completion of the doctorate. Rather, the issue is seen as one concerned with the actual amount and manner of distribution of the lapsed time doctoral recipients take to earn the degree. With the accelerating expan­ sion of man's knowledge and the increased need to gain control over it, less actual time spent on the doctorate is not seen to be as societally expedient as is the Laurence Vincent Lauth searching out, and alleviation of, those factors which contribute to its unnecessary prolongation. Historically, those variables which have been most strongly associated with prolongation of the doctorate fell readily into 6 general groupings— discontinuities of attendance, patterns of financial assistance and support, dissertation requirements, personal, and depart­ mental variables. Organization of the Study The primary focus, then, of the present study was an investigation of the significance of those Independent variables which a review of the literature had revealed as most influential in accounting for prolonged lapsed time periods in the pursuit of the doctoral degree. To this end, a doctoral recipient sample of 320 was drawn randomly from Michigan State University's degree granting departments for the academic years 196667 and 1967-6 8 . The testing by an Intercorrelation matrix of 34 research hypotheses formulated from 53 of the 90 original independent variables and the 3 depen­ dent time lapse variables followed. A second Intercorrelation matrix based on the total sample divided into 6 basic fleldB of study was then employed to test 4 research hypotheses. Finally, a Least Squares Stepwise Deletion procedure was undertaken Laurence Vincent Lauth resulting in the formulation of 3 multiple regression equations, one for each of the 3 dependent time variables. Major Findings of the Study Of the 3^ research hypotheses based on the total sample, 27 were found to be supported by the data with 8 of these correlating with one of the 3 dependent time variables at significantly greater than .50 revealing that those doctoral recipients with a greater lapsed time between B.A. and Ph.D. reception were found to have more total years of post-B.A. interruptions and greater lapsed time off-campus after the end of course work. Recipients who evidenced a greater lapsed time between entry to doctoral study and reception of the Ph.D. degree were shown to have greater lapsed time in interruptions during the Ph.D. program, greater lapsed time off-campus after the end of course work, fewer full-time terms, no prior doctoral language proficiency, a greater number of credits below the 800 level, and a lower Ph.D. Grade Point Average. Doctoral recipients exhibiting a lower Ph.D. grade point average also showed greater registered time from Ph.D. entry to reception. Two of the research hypotheses based on the 6 fields of study data were also found to be significant at the .05 alpha level revealing that doctoral students in the humanities, the social sciences, the professions, and education show greater lapsed time between B.A. and Laurence Vincent Lauth Ph.D. reception than do those In the biological and physical sciences, with those in education having the greatest lapsed time of the entire group. Finally, the 3 multiple regression equations revealed that registered terms and lapsed time until the passage of the second language; part- and full-time terms; lapsed time of interruptions during the Ph.D.; number of Institutions since the B.A.; age at entry to Ph.D.; number and total years of interruptions since the B.A.; citizenship; registered terms and lapsed time until course completion; lapsed time in residence and off-campus after the end of course work; career plans at the entrance to graduate school; student’s evaluation of the Importance of financial need for assistant ships; salary per year of post-Ph.D. degree job; and registered terms and lapsed time between the end of course work and the end of the dissertation predicted the lapsed times between B.A. and Ph.D. and Ph.D. entry to reception and the registered time from Ph.D. entry to reception at the .05 alpha level of significance.

Instead, the primary question is the actual amount of time it takes students to obtain the doctorate and the manner of this time distribution. The National Academy of Sciences Report^ notes that an impor­ tant aspect of the doctoral education process is the time needed to complete the degree or the time lapse from receipt of the baccalaureate to the completion of the doctorate. With the geometric expansion of knowledge and the increasing need to gain control over it, less actual time is not seen as educationally or even societally 7 debatable.

The National Academy of Sciences Report. in listing the total calendar time elapsed between year of bacca­ laureate and year of doctorate, shows large field dif­ ferences. The total median time for all fields for the years 1964 to 1966 is 8.2 years. The physical sciences and engineering have the shortest lapsed median time with 6.3 years, while the biological sciences follow with 7.3 years, the social sciences with 8.0 yearB, the arts and humanities with 9*5 years and the professional fields with 10.8 years.

Tucker concludes that although humanities students seem to take longer to earn the doctorate than do physical science students, the additional time is really a function of the amount of time they are not in school, once they begin their program, rather than a 11 longer doctoral program Itself.

And, If In fact, the needed time for the Ph.D. can be curtailed, graduate schools may be able to produce up to 50 per cent more Ph.D.'s every year without increasing facilities or teaching staff. 14 Purpose of the Study The purpose of this study Is to investigate those variables which a review of the literature postulates to have been consistently, and to a significant degree, most influential In prolonging doctoral study. Such an investigation will be specifically concerned with the lengthening effect of these factors on Michigan State University doctoral recipients' degree programs. Consequently, the following hypotheses in their research form were formulated for the total Michigan State doctoral recipients' sample: ■^Sidney L.

At the same time, these students possess certain differences which affect in varying degrees the duration of their doctoral study. A second basic assumption is that certain compari­ sons by field of study can be made and that there is a definable nature to each of these fields. It Is further assumed that such comparisons by field of study are both desirable and necessary to reveal the peculiar patterns among fields which in turn affect the length of doctoral study. Theory The theories which attempt to explain the problem of prolonged time in earning the doctorate are numerous. Keniston theorizes that financial problems stemming from 10 lack of fellowships and preventing full-time study, lack of an established and clearly defined 3 year program norm, the out-moded language requirement and final examination, and the unlimited scope of the doctoral dissertation are factors involved in unduly lengthening the time of 15 doctoral study. ^ Berelson reports lack of financial support as an important cause, with the problems sur­ rounding the dissertation secondary in importance* He emphasizes the lack of faculty encouragement, due, in part, at least to the candidates' usefulness to the faculty as teaching and research a s s i s t a n t s . ^ Carmichael disagrees with the primacy of the financial support factor maintaining the real reasons for the prolongation of doctoral study to be the unclarifled goals of graduate study on the part of departments, lack of clearly stated preparatory steps for foreign language and qualifying exams, unduly delayed faculty approval of the dissertation 17 and general faculty reluctance to puBh candidates.

Bent, “Fellowships, Assistantships, and Traineeships," in 11 the lack of proper financial support as the primary cause and strongly recommend more unencumbered service-free awards, especially fellowships and research asslstantshlps, Rosenhaupt asserts that what is needed for successful doctoral degree completion is sufficient support for full­ time attendance, high undergraduate ability, and high la motivational level. * Grigg also views academic ability as a success factor while deploring the inability of graduate schools to draw the potentially best students. 20 Davis agrees with Rosenhaupt's and the other above authors' lack-of-support reasoning as well as the need for attracting better students. Doing all one's graduate work in a single institution and the tightening up of the training process, as well as better orientation and articulation of the beginning and the end of the dootoral program, are also seen as shortening the doctorate duration. It is Davis' statistical findings which seem to establish the idea that married men with a family tend to take longer than others to complete their degree; and that low post-degree salaries and a reluctance to go from graduate school to a college teaching position is Graduate Education Today, ed. by Everett Walters (Washington, D.

Heard includes inherent differences among disci­ plines, vocational indecision, and lack of proper super­ vision of the dissertation as well as lack of funds, lack of program coordination, and low post-degree remuneration among his reasons for prolongation of 22 doctoral study. Heiss observed from her Berkeley study Interviews with Ph.D. students that a significant number of doctoral students seem to enter and pursue their studies with no time schedule or sequential pattern in mind. She noted a lack of planning and direction with a consequent loss of motivation and drive. At least half of the interviewees admitted they had drifted a year * before settling down to a definite target. Like Car­ michael, Heiss sees the need for establishing realistic limits for the completion of doctoral study as well as an increased role on the part of faculty in encouraging, 23 guiding, and prodding along procrastinating students. Wilson, in sampling over 1900 doctoral degree recipients representing over 120 graduate departments and 15 doctoral fields, lists 15 factors which were 21 James A.

The 6 factors which proved Influential for a significant per­ centage of the sample Include discontinuity of graduate attendance, work as a teaching assistant, nature of the dissertation topic, writing the dissertation off-campus, financial problems, and Inadequate preparation in languages. Wilson found the correlation between the median time lapse and the incidence of selected factors as lengthening Influences to be .83 for discontinuity of attendance, .81 for off-campus dissertation, and .72 for financial problems. He also reported that the responses of graduate deans and departmental representatives sug­ gested a pattern of variables affecting doctoral duration very similar to those of the graduates’ responses above. k These respondents, particularly the deans, pointed out the crucial importance of clarity of institutional and departmental requirements and expectations as well as the nature of the advisory relationship with graduate students. 2k Data from the National Academy of Sciences supports the relation to the time lapse of such factors as the doctoral field, amount of institutional transfer during graduate work, the decision to take a master’s degree, time of beginning of graduate work, graduate study ^ Wilson, op. cit.. pp. k 6 ~ k 7 1 56. i4 continuity and commitment (full or part-time), and sex. In addition, the NAS Report states that most fellowship programs have as a major goal the reduction of the baccalaureate-to-doctorate time span, thereby indirectly pointing up the influence of support level in shortening the time lapse. The NAS Report. however, cites data to negate the often held assumption that the doctoral time lapse Is lengthened in the case of a person who receives his baccalaureate from a non-doctoral undergraduate 2*5 institution. J Organization of the Study Ninety Independent variables will be run against as many as 3 dependent time lapse variables to determine the various strengths of association. In thlB fashion, significant relationships between certain variables and time lapses will be established for the sample of 320 Michigan State University doctoral degree recipients. In addition, the 6 basic fields represented will be analyzed to elucidate any associative bonds, existing by reason of these fields* peculiar natures, between the appropriate dependent and Independent variables. Chapter I has presented the rationale for, and relevance of, the study of length of doctoral degree programs. Chapter II reviews the literature and discusses ^ N a t i o n a l Academy of Sciences, op. clt.. pp. 64-77, 15 the related ideas concerning the prolongation of doctoral study, Chapter III offers an analysis of the 90 inde­ pendent and 3 dependent variables together with the nature and source of the data and the methodology employed to appropriately interpret the data. Chapter IV presents the results obtained from the analysis while Chapter V presents a summary and states the conclusions. CHAPTER II REVIEW OP THE LITERATURE AND RELATED IDEAS A great diversity of reasons has been reported by many authors in support of the differences in the time lapse between the baccalaureate and doctorate. An analysis of their studies reveals, however, certain factors which are most frequently cited and more heavily supported by data. Discontinuities of Attendance Wilson reported the factor of discontinuity of attendance to be first in influence in the lengthening of the doctorate time lapse, both in the view of the graduate deanB and faculties and of the more than 1900 doctorate respondents (32 per cent ranked it first). Wilson further reported a .83 correlation between the median time lapse and the Incidence of this factor.1 The National Academy of Science data show that the differences in time lapses between broad fields are sharply reduced when total registered time is used (5*1 years for physical sciences to 6.8 years for education). ^Wilson, op. c i t .. p. 5 6 . 16 17 Thus, a major cause for prolonging the time lapse Is the Interrupting of the actual study time. NAS*s data support a relationship Moreover, between Increased time lapse and taking a bachelor's, master's, and doctorate at different Institutions. 2 The data also confirm the assumption that those who omit the master's degree finish in less lapsed time In all fields. In the "Total All Fields" category, even registered time elapsed In median time ranges from .7 years to 1.6 years less for those omitting the master's degree. In addition, delayed entry into graduate study causes prolongation in various fields with the physical sciences having only .2 median years delay but eduoation showing 1.0 median years delay. Wilson reports that the incidence of delayed entry (of at least 6 months) into graduate school across all fields and all respon­ dents is at the 34 per cent level. cent of his sample Thirty-seven per of respondents report one or more interruptions in their doctoral study of at least 6 4 months duration. Beach points out that 83 out of 100 undergraduate Btudents have high orientation toward further study and that 77 actually intend to go on, yet p National Academy of Sciences, op. c l t .. pp. 64, 79. 3Ibid. ^Wilson, op. cit.. p. 64. 18 only 25 per cent of college graduates actually enroll In graduate and professional school Immediately upon graduation.^ Heard reports In his summary of the Southern Regional Education Board study that, in regard to the timing of the graduate study goals variable, pursuit of graduate study became an objective only after senior year in college for 38 per cent of the slow group as com­ pared with 15 per cent of all the others. Correspondingly, only 47 per cent of the slow students went into graduate study within 6 months of college graduation, whereas 84 per cent of the fast students had. Moreover, Heard states that the doctoral degree had become an objective for the slower 65 per cent of students by the end of V the first year of graduate study as compared to 87 per cent of the faster students.^ Wilson reports from his investigation that for more than 27 per cent of all baccalaureate graduates pursuit of graduate training had not yet become established as a definite personal goal. Among English baccalaureates, the percentage soared to 42 per cent. By the end of the college senior year, interest in the field of doctorate was established across all fields at the 76 per cent level, ^Beach, op. clt.. p. 119. ^Heard, op. clt.. pp. 9-10. 19 but the definite personal goal of earning a doctorate 7 was indicated by only 30 per cent.' Patterns of Financial Assistance and Support Data from the Tucker study show that because of their financial situation, 35 per cent of the doctoral students surveyed were forced to extend their length of time In doctoral study. When respondents were asked to identify the single most important reason for not yet receiving their degree, the greatest number (19 per cent) reported lack of sufficient finances, followed o by 12 per cent who listed family responsibilities. The doctoral recipients in Wilson's study rated the factor of financial problems fifth, with over 27 per cent finding it lengthening their programs. In sources of financial support which were considered to be of major importance during their beginning and advanced stages of study, veterans1 benefits, teaching assistantships, research assistantships, and spouses* earnings led all bthers by a large margin. Of the respondents over-all fields, nearly 64 per cent held teaching assistantshlps with a mean duration of 2.0 years, while 7 ~ 'Wilson, op. clt.. pp. 64-66. 8 Tucker, Gottlieb, and Pease, op. clt., pp. 230, 255. 20 nearly 43 per cent held research assistantships with a g mean duration of 2.0 years. Tucker, Gottlieb and Pease report, similarly, that among doctoral recipients, the teaching asslstantshlp was a financial source cited by 60 per cent; 39 per cent listed the research asslstantshlp and about 50 per cent reported some type of fellowship or scholarship stipend.*0 Davis too, in his sample of over 2800 respondents representing 140 graduate institutions, in 1958, reported that the characteristic source of income for the majority of graduate students was stipends, i.e., scholarships, fellowships, and assistantshlps. Over 70 per cent received stipend income, with 4l per cent receiving half or more of their total income from stipends. For approximately 25 per cent of Davis* students, spouse income was an important source, while for only a small minority was full-time employment a major source of income. About 50 per cent of the sample had a non-duty stipend and 40 per cent had a duty stipend, i.e., one for which they had to perform some kind of service. Teaching assistantshlps were twice as common as research assistant­ shlps, with 25 per cent holding the former. Natural ^Wilson, op. cit.. pp. 79* 86-87. *°Tucker, Gottlieb, and Pease, op. clt., p. 214. 21 science students had the higher probability of holding a stipend of any type and received more money from their non-duty stipends. 11 In the advanced stages of doctoral study, the teaching assistantshlps were the most Important source of support, and yet, nearly 32 per cent of Wilson's sample cited the teaching asslstantshlp as a lengthening factor in their programs, giving it second position in 12 the ratings. Wilson further states that a correlation of .91 exists between the Incidence over fields of teaching assistantshlps and their rated "lengthening effect," whereas in the case of the incidence of research assistantshlps and their rated "lengthening effect," the correlation is but .54. Moreover, the relationship * over fleldB of the incidence of research assistantshlps and the median "entry to doctorate time lapse" was a negative .55. As a result, Wilson concludes that the role of the teaching asslstantshlp is perceived as financially sustaining, but not directly Instrumental, while the research asslstantshlp is perceived as both sustaining and directly instrumental to the completion of the doctorate.^3 11Davis, op. c i t .. pp. 126-128, 12 Wilson, op. cit., p. 48. 13Ibid., pp. 91-92. .. 22 Elder In his 1958 study of Harvard graduate students found that 5 per cent of the doctoral students in natural science, 13 per cent In social science and 14 per cent in humanities were delayed considerably by lack of money. Moreover, Elder noted that teaching assistantshlps delayed considerably 12 per cent of natural science doctorates, 8 per cent of social science,and 16 per cent lli of humanities doctorates. Tucker, Gottlieb, and Pease remark that the finan­ cial situation is more austere for the humanities and social sciences and seem to think that the nature of the disciplines and the characteristics of the individuals in them also influence both the amount of attrition and 1*5 the time it takes to earn the degree. v Although 43 per cent of humanities graduates reported fellowships as compared to 40 per cent in the physical sciences, the average total value of the latter was more than 50 per cent h i g h e r . ^ Thus, it is possible that if the fellowship support is significantly high, the median lapsed time for the doctorate could be affected in the direction of less lapsed time. 14 J. P. Elder, A Criticism of the Graduate School of Arts and Sciences in Harvard University and Radcllffe College (Cambridge. Mass.; Harvard University, 1938), p. 2l7 15 Tucker, Gottlieb, and Pease, op. cit.. p. 50. ^Wilson, op. c i t .. p. 89. 23 Arlt seems to feel that the only really significant factor In his study was the fact that of the 755 students on fellowships under Title IV, 14 per cent were able to complete their Ph.D.'s in 3 years including summers. For him, then, a short but sustained span of adequate fellowship support is the major cause of finishing the doctorate within the "expected" time, i.e., 3 years. A discordant note in the assistance picture is struck by Berelson in reporting the responses to his questionnaire on graduate education. He states that 4l per cent of the graduate deans, 30 per cent of the graduate faculty and 36 per cent of the recent doctorate recipients agreed that major professors often exploit Ph.D. candidates by keeping them too long as research assistants. Rosenhaupt states in his Columbia study that, though greater financial support in itself cannot guarantee more rapid doctorate completion, generally students who must support themselves have less time to spend on their graduate training, and that an increase in fellowships will at leaBt shorten the time needed for degrees. He cites the case of Princeton (known at the time for allow­ ing only full-time graduate study and for its insistence on rapid doctorate completion) which, in 1956, gave 73 per cent of its graduate students fellowships or ■^Arlt, op. cit., p. 241. 18 Berelson, op. clt.. p. 162. 24 assistantshlps as compared with the national figure of 24 per cent. Rosenhaupt's survey reveals, In addition, that Columbia's fully supported group of veterans com­ pleted the doctorate more rapidly than the non-veterans, in some cases by as much as 2.3 median years. Remarkably, the time gains were most pronounced in the 2 areas where non-veterans received the least support and least pronounced where 60 per cent of all students received aid.19 Lack of funds is also seen by Perkins and Snell in their study of historians to be a main problem of their sample of candidates. Their data reveal that 42 per cent of the 1958 Ph.D.'s completed their residence in graduate school in 3 years or less and 75 per cent 4 within 4 years. Yet doctoral programs of 8, 9, 10 and sometimes more years are not usually caused by time in residence, but by the needed full-time employment which, in turn, delays completion. 20 Another facet to this lack of financial support factor is brought out by Rosenhaupt who points out that Columbia Ph.D. candidates in fields that offered high 21 post-degree salaries finished the degree rapidly. On the other hand, Davis reports that in the humanities 19Rosenhaupt, op. cit., pp. 61-62. 20 Perkins and Snell, op. cit.. pp. 179-188. 21 Rosenhaupt, op. c l t ., p. 75. 25 where low post-degree salaries were expected, candidates apparently showed a reluctance to leave graduate school for the unattractive financial incentives of college teaching positions. Davis concludes from his statistical data that the higher the current Income and the lower the expected salary for Ph.D. candidates, the greater the proportion of students who expect to take more than 5 22 years. In looking further at the question of student income, Davis discovered that the higher incomes are con­ centrated among married students. However, it is the family role position which is the major determinant of financial situations, with only the fathers appearing to have financial troubles due not to low incomes but to income sources which divert them from their studies. The fact that there is a strong negative relationship between amount of employment and course loads completed only tends to aggravate their situation. Davis points out, however, that regardless of employment or stage of study, older students and those with higher Incomes carried 23 lower academic loads. 22 Davis, op. cit.. p. 129. 23Ibid., pp. 124-125. 26 The Dissertation Requirement In Wilson's study, over 27 per cent of the doctor­ ate recipients reported both the nature of the disserta­ tion subject and the conditions under which it was com­ pleted as significant factors Influencing the prolongation of the doctorate. As a result, these 2 factors ranked second and third among the top 5. The formal approval of the dissertation topic occurred after more than 3.0 median years of attendance for over 37 per cent of the sample. Less than 12 per cent of the respondents reported completing the disserta­ tion prior to course and residence requirements, with over 7 per cent reporting no topic as yet chosen at that 2k time. Completion of the dissertation measured in lapsed time from the date of formal topic approval involved a mean Interval of more than 2.0 calendar years. For nearly 50 per cent of the sample, average time taken to complete the dissertation is related to median entry-todoctorate time lapse at .61. Moreover, using Berelson's median page length of the dissertation and comparing it with Wilson's median time between topic approval and com^ 25 pletion, a moderate correspondence of .65 is shown. 2k Wilson, op. clt., pp. 96-100. 25Ibld.. p. 102. 27 Berelson reports that in reply to one of his 'criticisms and reforms' statements, i.e. "Doctoral dissertations, at least outside the sciences are too long"— 71 per cent of the graduate deans, 32 per cent of the graduate faculty, and 27 per cent of the recent doctorate recipients were in agreement. Sixty-four per cent of the deans and 32 per cent of the graduate faculty and recent recipients agreed that too often the dissertation is made to be a major contribution to research rather than a manageable topic, Berelson had earlier reported that the median length of a dissertation in the biological sciences Is 108 pages, in the physical sciences 103 pages, but in the social sciences 226 pages, and in the humanities 283 pages. 27 ' Tucker, Gottlieb, and Pease go on to suggest that the number of pages in a doctoral dissertation will have a correlation with the amount of time it takes humanities and social sciences doctoral students to earn their degrees as well as be a reflection of the differences in the nature of their disciplines and their character?8 istlcs as individuals. 26 Berelson, op. c i t ., p. 289. 27Ibid., p. 181. 28 Tucker, Gottlieb, and Pease, op. c l t .. p. 50. 28 Wilson, in reporting data regarding the amount of time spent in full-time employment before dissertation completion, states that over all fields, 30 per cent spent 1.0 years or more in full-time employment between approval of the dissertation and its completion. He further found a relationship between rank of the field in terms of median entry-to-Ph.D. time lapse and the above 30 per cent of respondents to be .84, a correspon­ dence which is consistent with Wilson's graduate sample who assessed the "off-campus dissertation" as a lengthen­ ing influence. Finally, because the natural science recipients spent more time on campus during the critical dissertation phase (37 and 28 per cent of the biological and physical science students spent 2.0 years or more as against 3.6 and 15 per cent of those in the social sciences and humanities), they enjoyed greater opportunity for holding research assistantshlps directly related and applicable to their dissertation (33 and 38 per cent in the biological and physical sciences in contrast to 16 and 2 per cent in the social sciences and humanities). Tucker found that it took their sample of Ph.D. recipients 2 years less to earn the degree than it takes the A.B.D.'s (All But Dissertation) not to earn the degree. The average lapse of time for the A.B.D.'s was 2^WIlson, op. c i t .. pp. 102-104. 29 29 6.0 years, ranging from 5*4 years in the biological sciences to 6.4 years in the humanities. 30 In addition, Tucker*s study reported that, as the quality (Tucker believes that there is a high correlation between doctorate production and quality) of a college decreases, the lapse of time between the beginning of post-master’s study and the obtaining of the doctorate increases, and the lapse of time for the A.B.D.'s between the beginning of post-master's study and the completion of all-but-the-dissertation increases. 31 The Language Requirement and Pre­ liminary (General) Examination Perkins and Snell view the foreign language require­ ment as a major obstacle to efficient Ph.D. completion reporting that only 14 per cent of all high school students in the nation study even one foreign language. 32 Seventy-one per cent of the graduate deans and 75 per cent of both the graduate faculty and recent doctorate recipients in Berelson's study agree that the foreign language requirement is, in most cases, ’’more form than substance," thereby giving this factor the greatest per- 33 centage of any response. J • Twenty-seven per cent of # 30Tucker, Gottlieb, and Pease, op. c i t .. p. 58. 31Ibid., p. 68. 32Perklns and Snell, op. c l t .. p. 184. 33 JJBerelson, op. c i t .. p. 289. 30 Wilson's respondents listed Inadequate preparation In language as lengthening their doctorates. Moreover, Wilson's data on the Incidence of a particular language studied as an undergraduate as compared to the per­ centage qualifying in that same language reveal a major source of the language problem. In all fields, 44 per cent studied French for their doctorate. Only 22 per cent of the total sample indicated no need for special preparation in any language. Of the German qualifiers, 6l per cent needed special preparation, as did 52 per ?4 cent of those in French. Departmental (disciplinary) differences in foreign language preparation and use do exist; only 14 per cent needed no special preparation in the social sciences, while 25 and 27 per cent needed none In the physical sciences and humanities respectively. As regards use, Berelson's study reveals that under 20 per cent in education, economics, and psychology reported professional use of a language, whereas 75 per cent or more was 35 reported for the physical and biological sciences. ^ In the Southern study, Wilson reported 23 per cent listing inadequate preparation in a field as a lengthening factor and one of the measurable variables which exhibit this inadequate preparation is the preliminary examination 34 Wilson, op. c i t .. p. 110. ^Berelson, op. c i t ., pp. 197-198. 31 In one*s discipline,^ Carmichael remarks that graduate students have been known to flounder for 2 years or more attempting to get ready for their general exams without knowing for what they were preparing. 37 ' Personal Variables Ability Ability is seen to have a definite temporal Influence by Berelson who states that the evidence sug­ gests that the ablest students tend to finish sooner and are more productive afterwards as measured by production qo of scholarly articles. The ability factor can be partially explained in terms of the ablest having more chance of getting support and attention. D a v i s 1 study k further concludes that 33 per cent of the .highest academic performance index group are postponing their graduate studies after their baccalaureate, thereby 39 depriving doctoral programs of abler students. ' Berelson's questionnaire results reveal 35 per cent of the graduate deans, 28 per cent of the graduate faculty, ^Wilson, op. cit., p. 47. 37 'Carmichael, op. c l t .. p. 150. 38 J Berelson, op. c i t .» p. 165. ^ J a m e s A. Davis, Great Aspirations (Chicago: National Opinion Research Center, University of Chicago, 1963), X, P. 317. 32 and even 25 per cent of recent recipients agree that the initial selection of graduate candidates is poor. 40 The grade point average at the Ph.D. level, as reported by Tucker is a better indicator of potential for completing requirements for a Ph.D. than the grade point average at the master’s level and the master's average is better than that at the undergraduate level. lil Age A wide range of departmental differences was shown to exist in the average age of graduates in the Wilson study. The median for all departments was 31.9 years of age, whereas history alone was 35.1 and chemistry iiP only 28.8. Rosenhaupt's study at Columbia reveals that a larger percentage of those who entered graduate study while young obtained Ph.D.'s than did those entering at a more advanced age. Yet, those who entered after 23 took less time to finish than did the younger candidates, with those over 29 finishing the fastest. 40 jiq Berelson, op. cit.. p. 290. lil Tucker, Gottlieb, and Pease, op. clt., p. 210. lip _ Wilson, op. clt.. pp. 36-37. JRosenhaupt, op. clt.. p. 75. 33 Sex Time lapse appears to vary by sex as well. Women have longer total time lapse than men in almost every field (identical in the physical sciences) and are more concentrated in fields with long total time lapses (arts and humanities and education where they take 10.8 and 16.0 years respectively, as opposed to 9*2 and 13.3 years for men). Moreover, a smaller number of women than men complete the doctorate with minimal interruption. As a result, the median age at the com­ pletion of the doctorate for women in all fields is 35 as compared with 31 for men. Again, only in the physical sciences, where women receive the doctorate at a younger median age than men (28.7 to 29-3 years of age), do k women finish with the same time lapse as men (6.3 44 y e a r s). v Departmental Variables The graduate deans in Wilson’s study ranked in second place factors connected with departmental expecta­ tions and faculty attributes. A major variable cited was the nature and degree of clarity of departmental expectations especially as seen through the major pro­ fessor's, advisor's-or thesis director's guidance, attitudes, and standards of progress. Changes in the iiii National Academy of Sciences, op. c l t .. pp. 111113. 34 dissertation committee, for example, was listed eighth (by more than 6 per cent) as a lengthening experience among the Southern sample of doctorate recipients. 45 The number of doctoral advisees per major advisor may well show a lengthening Influence within fields. Though the social sciences show a ratio of 1,88 doctorate recipients per advisor per 3 year period, psychology with the highest ratio (2.07) also possesses the shortest median time lapse from master's to Ph.D. (4,2 years). And anthropology and archeology, exhibiting the lowest ratio (1.65), have the longest time lapses (5*6 y e a r s ) . ^ Perkins and Snell reported that 300 history graduate students Indicated something less than satisfac­ tion concerning advice from professors— 46 per cent of li7 19 Ph.D.'s from one of these 7» Berelson reported that 38 per cent of the graduate deans, 35 per cent of the graduate faculty, and 43 per cent of recent recipients agreed that graduate students do not clearly know what they must do to get the doctorate and are not well counselled, i.e., experience Ill-defined expectations and Inadequate guidance. 48 ^ W i l s o n , op. c lt.. pp. 45-47. 46 p.

As noted earlier, the median rates of progress tend to be higher In departments where a higher proportion of recipients omitted the master's and in which smaller percentages Interrupted study upon lig master's reception. Finally, Poulton, In his study of doctoral programs at Michigan State University, reports time data on 729 successful degree recipients representing 70 different departmental programs or majors. He found that from doctoral admission date to completion of language requirements, 2.0 years were required; from admission date to completion of preliminary examinations 3.0 years were needed; from admission date to completion of all degree requirements 4.5 years were needed; and that the average number of terms registered during the doctoral program was 13*9. 50 His analysis of the lapsed and registered time required to complete the degree reveals a wide range of departmental differences. Accounting exhibits the least 40 7Wilson, o p . clt. . p. 25. ^°B, R.

Those variables more heavily supported by research *1 data fall readily into 6 general groupings— discontinuities . of attendance; patterns of financial assistance and support; the dissertation requirement; the language, course work, and general examination requirements; personal variables; and departmental variables. It will be, then, these general areas and the particular variables which compose them which will be analyzed through application of the Michigan State doctoral degree total sample data, and where appropriate, through field data. 51Ibid., Table 2, pp. 1-3. CHAPTER III GENERAL DESIGN AND METHODOLOGY The design of the study is treated in 4 general sections: (1) Sample, (2) Sources of the Data, (3) Nature of the Data, and (4) Analysis Procedures. Sample The population from which the sample was selected consisted of the doctoral recipients of Michigan State University during the academic years 1966-67 and 1967-68. Ten doctoral recipients from each of those Michigan State University departments which graduated at least 10 such students during the above years were then randomly selected except in those cases where there were but 10 recipients. In the latter instances, all 10 were selected. It was felt that the use of fewer than 10 degree recipients would not have provided sufficient data from which significant conclusions and/or Implications could be drawn. Requiring more than 10 recipients per depart­ ment would have narrowed the departmental scope of the study considerably. 37 38 As a result, the sample selected numbered 320, and represented 32 of the 57 Michigan State University departments that granted doctoral degrees during the 1966-67 and 1967-68 periodB. The division of these departments into 6 fields was based on similar categori­ zations as given in the reports of the National Academy 1 2 of Sciences and Tucker together with the particular organizational structure existing at Michigan State University (Table 3.1). Sources of the Data Data on the selected sample of doctoral recipients and their departments were collected from 6 different sources. The first source, graduate transcripts, was obtained for each member of the sample from the Office of the Registrar. The second data source, the Office of the Graduate School Doctoral Candidate Questionnaire and the Question­ naire for Candidates for Doctor's Degrees (Appendix), was obtained from the records of the School for Advanced Graduate Studies. The Application for Admission to Graduate Study, the third data collection instrument, was obtained in the Office of the Registrar's Non-Current Records Division. 1National Academy of Sciences, op. clt.. pp. 3-11 2 Tucker, Gottlieb, and Pease, op. clt.. pp. 22-2M. 39 TABLE 3.1.— Departments divided by field.

Scholarship, fellowship, and fee remission data, the fifth source, were collected from the Registrar's Non-Current Records Division, while the sixth source, asslstantshlp and other on-campus employment information, was taken from the Office of the Payroll. Nature of the Data Prom the 6 sources of data outlined above, 90 independent and 6 dependent variables were initially gathered on each member of the sample. The 90 inde­ pendent variables (Table 3.2) selected for analysis were chosen on the basis of the strong and frequent support granted them in the literature in the form of research data and/or experiential observation. Thus, each of the 90 independent variables align themselveB under one of the 6 general categories described in Chapter II. In addition, the Bource of, and data format under which, each variable wascollected for measurement and analysis is listed in Table 3*2. The 6 dependent variables selected were also chosen because of the frequent evidence in the review of the literature of their usefulness and appropriateness in measuring the time spent by doctoral students in their pursuit of the Ph.D. They were: TABLE 3.2.— Independent variables.

Analysis Procedures Factor analysis, correlational analysis, the t-test of significance, and multiple regression analysis were the 4 basic procedures employed In the statistical treatment of the data. Since this study deals with a population that has already achieved their doctoral degrees, and therefore cannot further be manipulated, the analysis of the data cannot focuB on an Investigation of any direct causality between the Independent variables and the dependent variables of time between the baccalaureate and the doctorate. Rather, the analysis of the data will Involve a determination of the varying strengths of the functional 46 relationships between the dependent variables and the various Independent variables listed In Table 3.2. In order to avoid as much as possible overlapping measures and to insure more independence in the dependent variables used, factor analysis was employed using Michigan State University's Computer Institute for Social "3 Science Research (CISSR) routines. First, a 6 by 6 correlation matrix routine was run, which in turn served as input for the Factor A program, The Factor A routine produced a principal axis Quartimax and Varimax rotation analysis which indicated the use of less than the original 6 dependent variables. Then, as the second step toward testing 34 of the 38 hypotheses stated in Chapter II, a 93 by 93 correla% tion matrix was run involving the 90 independent vari­ ables and the 3 dependent variables using the CISSR 4 IDCORR routine with adjustment calculations made for missing or non-applicable data. From the above correlation coefficients generated by the correlation matrix, the 34 hypotheses were then o JA, Williams, "Factor Analysis Factor A: Principal Components and Orthogonal Rotations," Technical Report No. 34 of the Michigan State University Computer Insti­ tute for Social Science Research, East Lansing, Michigan, October 23» 1963.

In addition, the remaining Independent variables were subjected to the t-test to determine their signifi­ cance with each of the dependent variables. After the above correlation matrix was run on the total sample, a second correlation matrix employing the identical routine was run on the 6 fields which comprise the total % sample. The resulting correlation coefficients were tested for significance in the same manner as those of the total sample and included the testing of Hypotheses 35, 36, 37, and 38. Finally, in order to obtain a multiple regression equation capable of predicting an unknown time lapse for a doctoral student given the knowledge of his score on one or more known variables, the following statistical procedures were undertaken. First, to provide a simplified description of the relationships between the 90 independent variables, F U8 thereby facilitating an interpretation, comprehension, and management of such a large collection of items, the CISSR Factor Analysis routine was again employed. Four­ teen of the 90 variables which exhibited more than 30 missing or non-applicable observations were taken out and each of those items having fewer than 30 were supplied with the mean of the particular variable's total observations. The above adjustment of the data was necessary since the succeeding Least Squares Deletion analysis (LSDEL)^ permits no missing data. Factor analysis with an absolute criterion of 28 (28 factor rotation) was then run for a principal axis, Varimax, and Quartimax analysis on the 76 dependent variables. The next step planned was to use as raw data for the Least Squares Deletion analysis only those variables which loaded highest on the rotated factors. However, a preliminary test run of the Least Squares analysis revealed the presence of at least one negative regression coefficient where a positive one was expected, Indicating the possible influence of suppressor variables. If one or more suppressor variables were operating, it would be possible that an Independent variable, though ^Mary E. Rafter, and William L. Ruble, "Stepwise Deletion of Variables from a Least Squares Equation (LSDEL Routine)," STAT Series Description No. 8 of the Michigan State University Agricultural Experiment Station, November, 1968. (Mimeographed.) 49 correlating only slightly with the dependent variable Itself, could, through the difference between it and a second variable (even one with a negative correlation), add significant predictability to the regression equation. Consequently, to preclude the possibility of losing negative correlations from the regression analysis, not only were the variables loading highest on the rotated factors included, but all of the 76 variables as well. Summary A doctoral recipient sample was drawn from Michigan State University's degree-granting departments for the academic years 1966-67 and 1967-6 8 . To determine the differing strengths of the relationships between the 3 dependent and the Independent variables aB stated In the 38 hypotheses, an Intercorrelation matrix generating correlation coefficients both for the total sample and for the 6 fields was utilized. Then, in order to develop a multiple regression equation capable of predicting a doctoral student's time lapse period needed to obtain his Ph.D. degree, factor analysis procedures on 76 selected variables were employed, followed by, a Least Squares Regression analysis. CHAPTER IV STATISTICAL ANALYSIS The present chapter describes the statistical procedures and results of (1) the factor analysis of the 6 dependent time variables; (2) the correlational analysis of the 90 independent variables with 3 dependent variables together with the corresponding t-test of significance results including the testing of the 34 hypotheses; (3) the results of the principal axis, Quartimax, and Varimax rotations of the factor analysis on 76 Independent variables; and (4) the predictive equations determined from the Least Squares Regression Analysis from the 76 independent and 3 dependent variables. Dependent Variables Though 6 dependent variables were Initially selected (p. 5 2 ) as potentially useful in yielding significant relationships with the 90 independent vari­ ables, 3 were expected to yield information more useful to this study. The f i r s t , Lapsed Time: B.A.-Ph.D., w a s .chosen because it basically covers the total period of time most directly connected with the pursuit of the doctorate. 51 The second, Lapsed Time: and third, Registered Time: Ph.D. Entry-Reoeption. Ph.D. Entry-Receptlon. were selected both on the basis of their general importance In covering the period of time during which actual doctoral level study was being conducted, and on their specific potential significance for Michigan State University as the institution concerned in the doctoral degree-granting programs. Consequently, the Lapsed Time: Ph.D. Entry- Receptlon variable was seen as the most significant phase of the total B,A.-Ph.D. time period, while the allied Registered Time: Ph.D. Entry. Reception was similarly viewed as important in permitting distinction in the relative associative strength between time actually enrolled and actual total lapsed or calendar time. ; At this point, factor analysis was utilized to aid in a closer examination of the underlying association that might have existed between the 6 original dependent variables and to support the reduction of their number to an expected and more manageable 3. The resulting factor analysis consisted of a 3 factor rotation since an earlier analysis had shown that only the eigenvalues of these first 3 factors were 1.00 or above (Table 4.1). Both the Quartimax and Varimax rotation analyses yielded the highest loadings on 1 A, Williams, op. c i t . TA31E *.1 FACTOR ANALYSIS OF THE Six' DEPENDENT VARIABLES I.

The third factor on which Variable 1 as well as 4 and 5 loaded accounted for another 23 per cent (Table 4.1). Since Variable 1 was represented in Factor 3 with a relatively high loading (-.53)* Variables 4 and 5 were no longer viewed as essential for this study and were dropped from further factor analysis. A second Quartimax and Varimax rotation using a 2 factor solution on Variables 1, 2, 3, and 6 yielded the expected 2 eigenvalues of 1.00 or above with the 2 factors accounting for over 80 per cent of the total variance (Table 4.1). The highest loadings under Factor 1 were on k Variables 2 and 3 and on Factor 2 on Variables 1 and 4 (Table 4.1). And, since dependent Variable 1 covered the entire B.A.-Ph.D. period, it was selected as more suitable than Variable 4 for this study. The above factor analysis, then, supports the reduction of the initial 6 dependent variables to the 3 variables most appropriate and germane to the present study. Correlational Analysis: Sample Findings Total Each of the selected dependent variables were then run against the 90 independent variables as outlined in 54 Table 3.1 to determine the level of associative strength 2 that existed between them on the total sample of 320. The findings in the form of means, standard deviations, degrees of freedom, correlation coefficients, and the t-tests of significance results are given in Table 4.2. Consequently, all those variables (one or more) connected with each of the 34 hypotheses were tested at the .05. level of significance using the critical values of the correlation coefficient. Of the 34 hypotheses tested for the total sample in the null form p « 0, 27 permitted the rejection of the null hypothesis (Table 4.2) (Hypotheses 1, 2, 3, 4, 6, 7, 8, 9, 10, 12, 15, 16:, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, k20, 29, 30, 31, 32). In these cases then, the null hypothesis was rejected at the ,05 level and the data supported the research hypothesis that p is significantly different than zero at a 95 per cent level of confidence (Table 4.2). The data did not support the remaining 7 hypotheses when tested at the .05 alpha level (Hypotheses 5, 11, 13, 14, 18, 33, 34). As a result, the null hypothesis was retained in these Instances. In addition, in 8 of the 27 significant hypotheses (Hypotheses 2, 3, 4, 6, 17, 20, 21, 23), the data 2 o David Kline, op. cit. JGeorge A.

Finally, Factor 27, Field and Institutional Change, had a 2 variable loading with Number of Field Changes, Variable 1, the higher at -.709. Of the 76 variables loading on the 28 factors, all 76 loaded high on one of the factors so, though it would have been possible, as initially planned, to select out for the Least Squares Regression routine one or more of the highest loading representative variable members of each factor, the possibility of the presence of "suppressor" variables made a more conservative 122 approach desirable. c In fact, the technique of factor analysis discussed above was employed Initially to reduce the number of 76 available, useable predictor variables and use some of the resulting factors In a regression equation in place of the original variables. Nevertheless, when reliable variables such as age or lapsed time of various kinds are used as they are in this study, it could happen that factors which account for very little variance in the predictor variables could still be highly useful in predicting the dependent variables. In other words, given 2 original variables that are highly correlated as Lapsed and Registered Time until Passage of the Second Language (.7 8 ), the factor consisting of the difference between the scores of these 2 would account for little variance in the original 2 variables. Yet such a difference might have had a strong influence on the time lapse and thus correlate more highly with some external criterion than would a factor consisting not of the difference but of the sum of the 2 scores on registered and lapsed time. Consequently, to avoid such potential loss of pre­ dictive power, the strategy of stepwise regression based on the use of the original variables as input data was selected.

Such a technique of choosing all the 76 Independent variables avoids the danger of losing the added pre­ dictability of what Darlington describes as "suppressor" variables. He defines a suppressor variable as one which, when included In a regression equation In which the variables have been scored in the direction which makes their correlation in the population positive, nevertheless, takes on a negative weight when the regresBlon equation is derived for the population, 7 The Least Squares Regression Analysis The Least Squares Regression routine employed con­ sisted of a stepwise deletion in which an initial least squares equation was formed using all of the independent variables. Then, the variable out of the total least useful (significant) to the prediction was deleted from the equation and a new least squares equation estimated. The process continued until only those variables remained which were selected as candidates for deletion 6Ibid., p. 18. ^Ibld., pp. 5-7* 124 but were found to be significant at the .05 level and thus retained. As mentioned earlier, 76 independent variables were initially selected as candidates for the least squares routine. Variable 31* Age at End of Ph.D.. however, was dropped Just prior to the computer run because it was viewed, due to its post-hoc nature, as incapable of serving as a meaningful or useful predictor. Three Least Squares Deletion routines were then performed each on a separate computer run using the 75 independent variables and one of the 3 dependent variables for each pass. ficients and beta The resulting regression coef­ weights and their standard errors, P critical values and their significance levels, the partial correlation coefficients and the R 2 deletes together with the multiple correlation coefficients p (R and R ) and the standard error of estimates for those independent variables which met the .05 significance level criterion are listed in Table 4.5.

In analyzing the 11 predictor variables, normalized weights (beta weights) rather than the regression coef­ ficients (Table 4.5) were employed as more useful and accurate in normalizing the raw scores of the sample, thereby reducing the amount of predictive fluctuation due to large standard deviations. These beta weights, then, do not change when an independent variable is multiplied > by a constant resulting in an indication of the contribu­ tion of each independent variable as "predictor” or "accounter" for the variation of the dependent variable. 2 Partial correlation coefficients and R deletes were also reported since they are both useful in approximating the portion of variation which each of the independent variables accounts for in the dependent variable. Variable 34, Age at Entry to Ph.D.. proved to carry the highest beta weight (.545) with a partial correlation coefficient of .612, indicating rather high usefulness as a predictor of the variation of the dependent variable. 129 Variable 80, Total Years of Interruptions. showed a .367 beta weight and a partial correlation of .407. The third highest beta weight, .239, was assigned by the Least Squares Regression Equation routine to Variable 23, Lapsed Time of Ph.D. Interruptions, which also was assigned a rather high predictive measure of .361. Variables 7 and 6 respectively, Lapsed and Registered Terms until Passage of Second Language, carried the next highest beta weights (-.148 and .111). The presence of the negative beta weight is, as discussed earlier, at first view, disconcerting. Variable 7 had correlated significantly and positively (.1 7 6 ) with the dependent variable, Lapsed Time: B.A.-Ph.D. What has happened according to Darlington is that precisely because Variable 7 is measuring more of Variable 6 with which it corre­ lates highly than of the dependent variable, Lapsed Time: B.A.-Ph.D., it receives a negative weight. In other words, Variable 7 is more useful as a predictor in the regression equation as a measure of what Variable 6 O doesn’t measure in the dependent variable. The nature of what is being suppressed in 6 that 7 is better at predicting is not easily determined. In fact, Darlington maintains that it is extremely hazardous to reasonably interpret negative or suppressor 8Ibid., p. 4. 130 relationships in a complex multi-predictor situation. And yet, he concludes that it would be difficult to imagine a researcher with such faith in his ability to conceive of all possible suppressor relationships that he would ignore the Improved predictability of negative beta weights. q Variables 8, Registered Terms until Passage of the General Exams, and 79, Number of Interruptions B.A.-Ph.D., also were assigned negative beta weights (-.142 and -.129). Both are interpretable in the same terms as discussed above; the General Exams variable, in leaving the time lapse part of its correlation to Variable 6, takes on a negative character to be more useful as a predictor of Lapsed Time: B.A.-Ph.D. Variable 79 operates in the same fashion leaving to Variable 80 the lapsed time variance to add its negative weight to greater predictability. Finally, Variable 26, Number of Institutions since B . A . (.096), and Variable 90, Citizenship (.130), finish up the significant predictors for dependent Variable 1, Lapsed Time; B.A.-Ph.D. These 2 carry partial correlation coefficients of .219 and .130 respectively. At this point, after the last step in the analysis procedures has been taken, of the 75 it is 9Ibid., p. 5. 131 Interesting to compare those variables which correlated most highly with Lapsed Time; B.A.-Ph.D. in the correla­ tional analysis with those which thp Least Squares analysis reported as the best predictors. The 3 vari­ ables, 34, 79, and 80, with significant correlations greater than .50 for the total sample.correlational analysis also were selected as 3 of the heaviest weighted predictors. Yet, there were at least 11 other variables with higher correlations in the earlier rela­ tionship analysis which were deleted in the regression equation in favor of others of less apparent influence. For example, Full-Time Terms (.010 which is non­ significant) was selected over Number of Field Changes (.335) and Number of Children at End of Ph.D. (.441). Such a result serves to further clarify the function of the multiple regression equation to increase the precision of the prediction capability of the independent variables. The resulting regression equation for predicting Lapsed T i m e : B.A.-Ph.D. may be written Zy = . 1 1 1 ( Z 1 ) - , 1 4 8 ( Z 2 ) - , 0 9 8 ( Z 3 ) + . 2 3 0 ( z 1}) . . . + . 0 5 3 ( Z 1 1 ) where Z ■ the transformed (normalized) score of a doctoral student*s expected Lapsed Time; B.A.-Ph.D. and Z^ . . .

The standard error of estimate was but 1.43. m Variables 10, Part-Time Terms, and 11, Full-Time Terms. wi£h beta weights of .333 and .200 respectively exhibited usefulness as predictors as measured by partial correlation coefficients of .468 and .137* Variable 23* Lapsed Time of Ph.D. Interruptions, with the highest beta weight (.446) carried a partial correlation coefficient of .463. Variable 22, Lapsed Time Off Campus after End of Course Work (All But the Dissertation) and 21, Lapsed Time In Residence after End of Course Work, with beta weights of .320 and .165 respectively, carried partial correlation coefficients of .371 and .339. * Variable 7* Lapsed Time, and Variable 6, Registered Time until Passage of Second Language, reverse the functions they had for predicting dependent Variable I. Here, Variable 7 instead of being negative was positive (.105)* while Variable 6 changed from positive to negative (-.090). 133 Variables 13* Lapsed Time until Course Completion, and 12, Registered Terms until Course Completion, earned beta welghtB of .202 and .137 respectively and carried partial correlation coefficients of .292 and ,137. Both Salary per Year for Ph.D. Job (88) and Career Plans at Graduate Entrance (36) had negative beta weights of -.122 and -.124 respectively. Finally, Variable 48, Importance of Financial Need for Assistantships. was assigned a beta weight of .138. Again, as in the case of the Lapsed Time: B.A.- Ph.D. dependent variable, those independent variables that correlated at a significance level greater than .50 (Variables 13, 22, and 23) also were selected by the Least Squares Regression analysis as the best predictors. * Similarly though, other variables that correlated sig­ nificantly were deleted, e.g., Number of Ph.D. Credits (.347) for such non-significant correlations as Salary of Ph.D. Job and Career Plans at Graduate Entrance. Once again the principle of the regression equation was operating to choose the measures of prediction and not necessarily of correlation.

The standard error of estimate was 1.27* Variables 10, Part-Time Terms. and 11, Full-Time Terms. received beta weights of .776 and .428 respectively. Part-Time Terms, then, had a very high usefulness-aspredlctor rating of ,511 while Full-Time Terms carried a high rating of .467. Variables 7, Lapsed Time until Passage of Second Language, and 6, Registered Time until Passage of Second Language, were assigned beta weights of -.109 and .094 respectively and partial correlation coefficients of .137 and .125. Variables 12, Registered Time before Course Com* pletion, and 13, Lapsed Time before Course Completion, received beta weights of .137 and .084 respectively and carried rather low usefulness ratings Qf .117 and .120. Variables 15, Registered Terms between End of Course Work and End of Dissertation, and 1 6 , Lapsed Time between End of Course Work and Dissertation, received 135 beta weights of .10*1 and .075 respectively. Variable 15 carried a low usefulness rating of .117 while the latter variable had a partial correlation coefficient of .216, even though Its beta weight was lower. Finally, Variable 48, Importance of Financial Need for Assistantships. had a beta weight of -.041 and was assigned a partial correlation coefficient of -.149. A comparison of the above predictor variables with those of the 75 correlating highly with the dependent variable exhibits a general correspondence. But unlike those of the earlier 2 dependent variables, the predictor variables with the highest predicting capability (Vari­ ables 10, 11, 12, and 1 6 ) do not all have significant correlations greater than .5 with the dependent variable * Registered Time: Ph.D. Entry-Reception. For, Full-Time Terms (Variable 11) carried only a ,196 correlation and Variable 16, Lapsed Time between End, of Course Work and End of Dissertation carried but .284 while others such as Variable 8, Registered Terms until Passage of General Exams. with a correlation of .776 was deleted. Neverthe­ less, as happened in the earlier 2 equations, many variables which correlated higher than, for example, Variable 48 (-.04 and non-significant) were deleted including Variable 18, Number of Credits Taken before Organization of Committee (.253 and significant), and Ph.D. Grade Point Average (-.209 and significant). 136 Thus, the correlational significance of a variable does not necessarily correspond to its predictive usefulness.

Ill Summary , After the reduction of the original 6 dependent variables to 3 was supported by a 3-factor rotation followed by one of 2-factors (Table 4.1), a correlational analysis was run. (Lapsed Time; The 3 selected dependent variables B.A.-Ph.D.; Lapsed Tlmei Reception; and Registered Time: Ph.D. Entry>- Ph.D. Entry-Reception) together with the 90 independent variables for the total number of 320 were placed in an intercorrelation matrix to determine the varying strengths of relationship. Of the 34 hypotheses tested in this manner in the null form p » 0, 27 (Table 4,2) were found to be sig­ nificant at the .05 alpha level, thereby permitting the rejection of the null hypotheses In these cases and the conclusion that the data supported the alternate hypothesis that p is significantly different from zero. In 8 of these 27 hypotheses the data supported the con­ clusion that, at the 95 per cent level of confidence, p was significantly greater than .50 (Table 4.2), 137 In addition, of those 39 Independent variable? not tested by the 34 hypotheses, 23 correlated at the .05 alpha level as being significantly different than zero. Of these, 2 correlated significantly at greater than .50. Correlational analysis of the total sample popula­ tion divided into 6 fields or areaB of doctoral study followed (Table 4.3). In testing Hypotheses 35 and 36 (Table 4.3, Footnote 1), a one-way analysis of variance was employed followed by the Sheffd Test. hypotheses p1 * The null m V 3 ■ Vt\ m ^5 ■ alpha level were rejected and the data supported the alternate hypotheses. Hypotheses 37 and 38 (Table 4.3) were tested and the null hypothesis retained. A review of the findings concerning the correlations within the 6 fields (Table 4.3) Bhows the physical and biological sciences as having 42 variables with significant correlations and 45 non­ significant; the humanities, 44 significant and 43 non-significant; the social sciences and education, 37 significant and 50 non-significant. A factor analysis waB run on the 76 selected variables for the purpose of reducing the number of variables to be Included in the Least Squares Regression analysis. The 76 variables loaded on 28 factors with 2 or more variables loading only on 19 factors. To avoid loss of predictive power due to the likely presence of negative beta weights, not only were the 138 variables loading high on the 9 factors included in the Least Squares Regression analysis, but all 75 of the selected independent variables as well. Finally, the Least Squares Deletion routine was undertaken and multiple regression equations were generated for each of the 3 dependent variables. Dependent Variable I, Lapsed Time: B.A.-Ph.D.. produced 11 significantly predictive variables which with the con­ stant accounted for 84 per cent of the dependent variable's variation. Dependent Variable II, Lapsed Time: Ph.D. Entry-Reception generated 12 significant; predictor Variables that together with the constant was responsible for 97 per cent of the dependent variables' variation. Dependent Variable III, Registered Time; Ph.D. Entry- Reception. selected out 9 predictive variables that with the constant accounted for 93 per cent of that dependent variable's variation. CHAPTER V CONCLUSIONS AND IMPLICATIONS The primary focus of the present study was an Investigation of, and a testing for, the significance of those Independent variables which a review of the literature revealed as most Influential In accounting for prolonged lapsed and registered time periods in the pursuit of the doctoral degree,' Toward this end, a doctoral Recipient sample of 1 t 320 was drawn randomly from Michigan State University's degree-granting departments for the academic years 1966-67 and 1967-6 8 . Then, 34 research hypotheses were generated from 53 of the 90 original independent vari­ ables and the 3 dependent time lapse variables. These 34 hypotheses were tested in their null form, p ■ 0, at an alpha level of .05 by means of t-tests of signifi­ cance based on the results of an intercorrelation matrix. Twenty-seven of these hypotheses permitted the rejection of the null hypothesis. Eight of these hypotheses permitted the rejection of the null: Hq : p > .50 at? o * .0 5 . In addition, 23 of the remaining 37 Independent variables were found to be significantly associated 139 140 1 * with one op more of the dependent variables at the .05 level of significance. Two of these permitted the t rejection of HQ : p < .50. Next, an intercorrelation matrix was run on the 6 basic fields to search out the presence and strength of any relationships existing between the dependent time lapses and the Independent variables, but most particularly between those independent variables which generated Hypotheses 35, 36, 37* and 38. Hypotheses 35 and 36 were found to be significant at the .05 alpha level using a one-way analysis of variance, followed by a Scheff6 test. The 6 fields’ intercorrelatlonal matrix also pro­ duced the following results: the physical and biological ' i sciences’ fields showed 42 of the 90 independent vari­ ables correlating significantly different than zero with one or more of the 3 dependent variables. Fourteen of the biological science variables and 7 variables of the physical sciences correlated with one of the 3 dependent variables at significantly greater than .50. The humanities had 44 significant variables with 12 being significantly greater than .50. Both the social sciences and education reported 37 significant vari­ ables with the former having 8 variables correlating Blgnlfioantly greater than .50, and the latter having 14. Finally, the professions had 29 significant variables mi with m correlating with one of the 3 dependent variables at significantly greater than .50. The 6 fields share a significant correlation regard­ ing 11 independent variables of which 8 deal with the formal doctoral requirements, and one each with number of major advisors, doctoral study Interruptions, and family obligations. Three more were found to be significantly greater than .50 across all 6 fields. A factor analysis was then utilized on 76.of the 90 variables with a resulting 28 factor solution which produced high loadings of 10 on Factor 1 down through 1 on 7 factors. Factor 1 generated an eigenvalue of 7.79, while Factor 28 produced one of .912. The cumu­ lative proportion of variance attained .758 at Factor 28 with Factor 1 producing the largest single proportion of variance at .08. The above factor analysis, though it would have proven useful in reducing the number of potential pre­ dictor variables, was not employed directly in the final step of the study— formulation of multiple regression equations fop the 3 dependent time lapse variables. For, in order to preclude the possibility of overlook­ ing a valuable predictor that did not load high on one of the factors and which had the effect of a suppressor variable, all 75 of the independent variables were Included in the regression routine. 142 Thus, the Least Squares Stepwise Deletion procedure was utilized resulting In the generation of 3 multiple regression equations, one for each of the 3 dependent variables. Dependent Variable I, Lapsed Time! B . A .- Ph.D.. deleted all but 11 of the 75 Independent variables. These 11 had a squared multiple correlation coefficient (R^) of .847 with beta weights which were all signifi­ cantly different from zero at the .05 alpha level. Dependent Variable III, Lapsed Time: Ph.D. Entry- Reception, deleted all but 12 of the 75 independent variables producing a R of .974 and beta weights all significantly different from zero. Finally, dependent Variable III, Registered Time; Ph.D. Entry-Receptlon. 2 left remaining 9 predictor variables with an R of .928 * and beta weights that were aldo significantly different from zero. Conclusions The decisions based on the findings produced by the t-tests of significance were, in the following 27 hypotheses, t;o reject the null hypotheses p ■ 0 at the .05 alpha level and to conclude that the data support the following research hypotheses: 1. Doctoral recipients who exhibit late decision about, and lack of commitment to, their field of study goals, show a greater lapsed time between B.A. and Ph.D. reception than those who do not. 143 2.# Doctoral recipients with more total years of post-B.A. interruptions have a greater lapsed time between B.A. and Ph.D. reception. 3.» Doctoral recipients who show greater lapsed time in interruptions during the Ph.D. program, show greater lapsed time from Ph.D. entry to Ph.D. reception. 4.* The greater the lapsed time spent off-campus after the end of course work, the longer the lapsed time between B.A. to Ph.D. and Ph.D. entry to reception. 5. The greater the number of part-time registered terms required, the greater the lapsed and registered time required between Ph.D. entry and reception. 6.* The fewer the number of full-time registered terms required, the greater the lapsed and registered time required between Ph.D. entry and reception. 7. The fewer the number of quarters fellowship stipends are received during doctoral study, the greater the lapsed time between Ph.D. entry and reception. 8.

Implications for Future Research Due to the considerable amount of exploratory material subjected to analysis during this study, there remain many areas of study into which future researchers can probe more deeply and for which more significant results can be uncovered. Some of the more fruitful tasks requiring further examination include: 1. Replicate the study to test for validity of re­ sults of the Instrumentation and conclusions. Collect the data on the appropriate variables on a random sample of doctoral recipients since spring of 1968 and test out the predictive ability of the 3 regression equations formulated in this study. Do a cross-validation on the regression equations to ascertain true variance. 2. Replicate the study using all 6 dependent variables or a combination of say I, IV, and VI each of which loaded highest on one of the 3 factors in the 3 factor rotation performed In this study. 3. Determine the amount of interdependence existing between the 75 selected variables and select 15^ those with the greatest Independence for utilization in a correlation matrix containing the appropriate dependent variables as discussed in Number 1 above. 4. Experiment with a 15 factor rotation solution using the 75 selected independent variables, since in the study over 50 per cent of the cumulative variance has been accounted for by the time the 15th factor is determined (and whose eigenvalue is in excess of 1.4), 5. Using only the highest loading representative variable of each of the above 15 factors, run a correla­ tion matrix including the 3 and/or 6 dependent variables. 6. Execute a Least Squares Regression routine (a Least Squares Add as well as a Delete) using only those variables loading highest on the above 15 (or fewqr factors) as potential predictors. Such a pro­ cedure is done in the interest of having a smaller number of predictor variables in relation to the number of people in the sample, thereby aiding in a higher estimated true validity and a lower mean square error. 7. Replicate Numbers 4, 5, and 6 on each of the 6 fields but reduce the 15 factor solution to 7. A reduction in the number of variables required for the correlation run with the dependent variables as well as with the number of predictor variables required should keep the mean square error low and the true validity high in a sample with significantly less N. 155 8. Replicate Numbers 4, 5, and 6 on each of the 32 departments making up the total sample but selecting only 2 or 3 variables at most as correlators or predictors. And perhaps, consider either increasing the sample size in each department before using the least squares routine or employing another statistical method less prone to a small N in relation to number of variables. 9. Replicate Numbers 4, 5» 6» 7* and 8 but perform a factor analysis of both an orthogonal and oblique nature in order to generate factor scores to use as input data for the multiple regression equations. A comparison of these results with those of raw data input should determine the most useful predictive equation. 10. Replicate the study on the basis of the various institutional transfer patterns of doctoral recipients. 11. Replicate the study using departmental characteristics, especially those concerning the role of the major professor and departmental administrative style, especially as it pertains to allocation of departmental resources. 12. Finally, perform in depth interviews and/or case studies on doctoral recipients in conjunction with the above analyses to produce a more accurate interpreta­ tion particularly of personal variables influencing the dependent time lapses in the pursuit of the doctorate. r 156 It Is hoped that, such replication of, and further investigation into, the research material generated by this study, will enable administrators, faculty and students on individual as well as departmental and collegial levels to Increase both the efficiency and efficacy of doctoral programs.
