This study was designed to compare traditional and nontraditional full-time degree-seeking students' regression equations and validity coefficients across five Florida post-secondary institutions. The single multiple regression method with dummy variables was selected to compare the two groups' regression planes across institutions (FSU, UF, UCF, USF, and FAMU), within age groups, and between age groups within institutions. The multiple partial statistic was selected to test for the interaction effect between the two indicator variables (Age and Institutions) and the three main effects (HSGPA, SATV and SATQ). The across institutions and within age groups validity coefficients variability of the high school grade point average and the Scholastic Aptitude Test verbal and quantitative scores was investigated, using meta-analysis methodology. / A sample of 883 students was retrieved from the State University System (SUS) students' files. With the exception of age, all the students were selected to be equivalent on the following characteristics: full-time enrollment, first time in college, degree-seeking, and accepted under regular admission policies. This selection procedure limited the sample size of the nontraditional group of students and, therefore, generalizations regarding the results of this study should be made cautiously. / It was concluded that a common prediction system was not practical and that a separate prediction system should be developed for each of the two groups compared within the five postsecondary institutions included in this study. The findings showed possible systematic overprediction or underprediction of the nontraditional students' performance in college when using a traditional student-derived regression equation to predict nontraditional students' performance. It was also apparent that nontraditional students' high school grade point average and traditional students' Scholastic Aptitude Test quantitative validity coefficients varied from institution to institution. There was no variation across institutions or within age groups of the Scholastic Aptitude Test verbal validity coefficients. As expected, high school grade point average was a better predictor of traditional students' performance in college, as Scholastic Aptitude Test verbal was for the nontraditional students. The average validity coefficients of the nontraditional students were, in all but one instance, lower than for the traditional group. It was recommended that differential validity and regression systems for traditional and nontraditional students be routinely studied. / Source: Dissertation Abstracts International, Volume: 47-05, Section: A, page: 1706. / Thesis (Ph.D.)--The Florida State University, 1986.
