Direct Validation of Differential Prediction.
Lunneborg, Clifford E.
Using academic achievement data for 655 University students, direct validation of differential predictions based on a battery of aptitude/achievement measures selected for their differential prediction efficiency was attempted. In the cross-validation of the prediction of actual differences among five academic area GPA's, this set of differential predictors had only a slight advantage over a set selected to maximize absolute prediction of the five area GPA's. Three ways in which the effectiveness of differential prediction can be improved are presented. (Author)
