Real data are used to illustrate the comparison of two estimators for the square of a population correlation coefficient and the true validity of a sample prediction equation. Interpretive approaches to, and problems in, multiple correlation/prediction estimation are discussed. (Author/BW)

A method is presented for the construction of an artificial data set which will illustrate the behavior of the traditional, the negative, and the reciprocal suppressor variable in multiple regression analysis. It extends the method of Dayton (1972) and includes the previously reciprocal suppression defined by Conger (1974). (Author)

Major objective in this study was the structuring of a predictive model that would assess combinations of variables that most effectively and parsimoniously measure and forecast college success. (Author)

The t ratio used in testing the difference between two independent regression coefficients is generalized to the multivariate case of testing the difference between two vectors of regression coefficients. This is particularly useful in determining which of two variables best predicts a number of criterion variables. (Author/JKS)

The Structure-of-Intellect Tests are shown to represent promising alternatives to the traditional commercial standardized tests now widely used in predicting success in modern algebra. (Author/NE)

The Sixteen Personality Factor Questionnaire, Gordon Personal Profile, and Gordon Personal Inventory were administered to 151 male and female high school students. Multiple regression analysis indicated that the personality scales of each test could be predicted from the scales of the other tests. (Author/JKS)

The paper presented evidence of the criterion related validity of several Comprehensive Ability Battery (CAB) tests relative to criterion variables representing first year college achievement. Information regarding the criterion related validity of nontraditional tests of the CAB reflecting divergent production hypothesized to be associated with…

Factors seem to indicate that the OQS could be effectively substituted for the NTE as a screening measure for graduate students in education. The D-48 was not added to the prediction equation, since it made a negligible contribution to the total prediction. (Authors/CB)

Different approaches to defining suppression in multiple regression/correlation are compared, and their differences are illustrated. A test for determining the significance of a suppressor effect, which is based on the definition of suppression of W. F. Velicer, is extended to the general multiple predictor case and analysis of variance. (SLD)
