Abstract
Statistical procedures are presented for testing the homogeneity of regression slopes in multiple regression equations. The paper reviews the test for regression lines and provides equations for expanding this test to regression planes. Formuli are illustrated with two sets of multiple regression data, each with differing correlations between predictors. Results are discussed in terms of aptitude-treatment interactions in which there are two or more aptitudes for each treatment.Keywords
