While research has shown the statistical significance of high school grade point averages (HSGPAs) in predicting future academic outcomes, the systems with which HSGPAs are calculated vary drastically across schools. Some schools employ unweighted grades that carry the same point value regardless of the course in which they are earned; other…

This study sought to determine whether the use of standardized test scores contributes any useful information regarding First Time in College (FTIC) students' probable success at USF, using more detailed analysis of underrepresented minorities and women, who Micceri (2009) shows, experience substantial negative bias relative to males and whites on…

Findings show that the reliability of GPA depends on three factors: the number of course grades, the average reliability of these grades, and the credit-hour weights. (Authors)

This report addresses the problem of sample size in developing prediction equations for college freshman grade averages under the American College Testing (ACT) Assessment Program. For the ACT Assessment, the prediction weights are estimated by standard least squares procedures. Because prediction weights are estimated regression coefficients…

Predictor weights estimated by using multiple linear regression are biased when there is restriction in the range (RR) of the dependent variable. Standardized multiple regression yields partial correlations as weights for the predictors, and these can be corrected for range difference between calibration and application samples. However,…

First-year graduate students were asked to respond to a biographical questionnaire which emphasized motivational variables in addition to the usual demographic variables. It was hypothesized that the students could select from a group of ability measures the one best indicator of how well they would do in graduate school. To test this hypothesis…

The Graduate Record Examinations (GRE) Cooperative Validity Studies Project began in 1975 to fill the need for cooperation between graduate schools and testing agencies and for graduate level validity studies. More than 150 data sets from the 39 participating schools, representing over 19 fields of study, were analyzed. The data confirmed earlier…
