The relationship between academic success at DePauw University and such commonly used predictors as tested ability and academic success in high school was examined. The various subtleties of the multiple regression research method were also examined. Subjects were 1758 students who entered DePauw University during the fall semester of 1973, 1974, or 1975. Academic success was determined by the outgoing grade point average (OGPA) at the time the student left the school. Test scores included in the study were the verbal (SATVB) and the quantitative (SATQ) sections of the Scholastic Aptitude Tests. The scores from the battery of the College Entrance Examination Board achievement tests were also considered. Intercorrelations indicate that the scores for this study group are similarly related as they were for groups in previous research studies. High school rank tends to have the highest correlation with OGPA, and it is followed by SATVB. High school rank is relatively independent from the other scores, but the aptitude and achievement test scores are highly intercorrelated. Other correlations are anlayzed. It is concluded that the use of the multiple regression did result in a prediction equation that appears to be very useful in a pragmatic sense. Some problems with multiple regression are cited. (SW)
