am S~Us~dcs/BiostadsJdcs Programs In this chapter 64 research-doctorate programs in statistics/ biostatistics are assessed. These programs, according to the information supplied by their universities, have accounted for 906 doctoral degrees awarded during the FY1976-80 period--approximately 87 percent of the aggregate number of statistics/biostatistics doctorates earned from U.S. universities in this five-year span. On the average, 22 full-time and part-time students intending to earn doctorates were enrolled in a program in December 1980, with an average faculty size of 12 members.2 The 64 programs, listed in Table 8.1, represent 58 different universities. The University of Michigan (Ann Arbor), University of Minnesota, North Carolina State University (Raleigh), University of North Carolina (Chapel Hill), University of Pittsburgh, and Yale University each have one statistics program and one biomedical program (i.e., biostatistics, biometry, biomathematics, epidemiology, or public health) included in the assessment. All but nine of the programs were initiated prior to 1970. In addition to the 58 universities represented in this discipline, another 5 were initially identified as meeting the criteria' for inclusion in the assessment: Dartmouth College University of Illinois--Chicago Circle New York University University of Northern Colorado University of South Carolina Statistics/biostatistics programs at these five institutions have not been included in the evaluations in thin discipline, since in each data from the NRC's Survey of Earned Doctorates indicate that 1,038 research doctorates in statistics/biostatistics were awarded by U.S. universities between FY1976 and FY1980. 2 See the reported means for measures 03 and 01 in Table 8.2. 3As mentioned in Chapter I, the primary criterion for inclusion was that a university had awarded at least 5 doctorates in statistics/ biostatistics during the FY1976-78 period. 141
142 case the study coordinator either indicated that the institution did not at that time have a research-doctorate program in statistics/ biostatistics or failed to provide the information requested by the committee. Before examining the individual program results presented in Table 8.1, the reader is urged to refer to Chapter IT, in which each of the 16 measures used in the assessment is discussed. Summary statistics describing every measure are given in Table 8.2. For nine of the measures, data are reported for at least 61 of the 64 statistics/ biostatistics programs. For measures 04-07, which pertain to characteristics of the program graduates, data are presented for only 36 of the programs; the other 28 had too few graduates on which to base statistics.4 For measure 12, a composite index of the size of a university library, data are available for 50 programs; for measure 13, the fraction of faculty with research support from the National Science Foundation, the National Institutes of Health, or the Alcohol, Drug Abuse, and Mental Health Administration, data are reported for 37 programs that had at least 10 faculty members. As mentioned in Chapter II, data are not available on total university expenditures for research in the area of statistics and biostatistics--measure 14. Intercorrelations among the 15 measures (Pearson product-moment coefficients) are given in Table 8.3. Of particular note are the high positive correlations of the measures of the numbers of faculty and doctoral graduates (01, 02) with measures of publication records (15, 16) and reputational survey ratings (08, 09, and 11~. Figure 8.1 illustrates the relation between the mean rating of the scholarly quality of faculty (measure 08) and the number of faculty members (measure 01) for each of the 63 statistics/biostatistics programs. Figure 8.2 plots the mean rating of program effectiveness (measure 09) against the total number of FY1976-80 program graduates (measure 02~. Although in both figures there is a significant positive correlation between program size and reputational rating, it is quite apparent that some of the smaller programs received high mean ratings and some of the larger programs received low mean ratings. Table 8.4 describes the 135 faculty members who participated in the evaluation of statistics/biostatistics programs. These individ- uals constituted 71 percent of those asked to respond to the survey in this discipline and 17 percent of the faculty population in the 64 research-doctorate programs being evaluated.S More than one-third of the survey participants were mathematical statisticians and 16 percent were biostatisticians. More than half of them held the rank of full professor; almost two-thirds had earned their highest degree prior to 1970. 4 As mentioned in Chapter II, data for measures 04-07 are not reported if they are based on the survey responses of fewer than 10 FY1975-79 program graduates. 5 See Table 2.3 in Chapter TI.
143 Two exceptions should be noted with regard to the survey evaluations in this discipline. The biostatistics program in the School of Public Health at the University of Michigan (Ann Arbor) was omitted on the survey form because at the time of the survey mailing no information on this program had been provided by the institution. At the request of the study coordinator at this university, the program has been included in all other aspects of the assessment. Shortly after the survey mailing it was called to the committee's attention that the name of a faculty member in the statistics program at the University of Rochester was not included on the survey form. The department chairman at this university contacted other department chairmen in the discipline informing them of this omission. To assist the reader in interpreting results of the survey evaluations, estimated standard errors have been computed for mean ratings of the scholarly quality of faculty in 63 statistics/ biostatistics programs (and are given in Table 8.11. For each program the mean rating and an associated "confidence interval" of 1.5 standard errors are illustrated in Figure 8.3 (listed in order of highest to lowest mean rating). In comparing two programs, if their confidence intervals do not overlap, one may conclude that there is a significant difference in their mean ratings at a .05 level of significance.6 From this figure it is also apparent that one should have somewhat more confidence in the accuracy of the mean ratings of higher-rated programs than lower-rated programs. This generalization results primarily from the fact that evaluators are not as likely to be familiar with the less prestigious programs, and consequently the mean ratings of these programs are usually based on fewer survey responses. programs. This 6 See pp. 29-31 for a discussion of the interpretation of mean ratings and associated confidence intervals.
