In an effort to standardize academic risk assessment, the NCAA developed the graduation risk overview (GRO) model. Although this model was designed to assess graduation risk, its ability to predict grade-point average (GPA) remained unknown. Therefore, 134 individual risk assessments were made to determine GRO model effectiveness in the…

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)

An empirical method called Predicted Error Sum of Squares (PRESS) is advanced and studied. This method is used to examine the cross-validated prediction accuracies of some popular algorithms for weighted predictor variables. The weighting methods that were considered were ordinary least squares, ridge regression, regression on principal…

Since the Bureau of Labor's cost-of-living statistics are available for only 40 standard metropolitan statistical areas (SMSAs) in four regions, the author presents a method to estimate family budgets for all SMSAs. Data for the calculations are easily accessible in Census and other government publications. (Author/KC)

Data from the areas of job satisfaction and job stress are used to illustrate the following points: (1) that measurements can be arranged conceptually along a continuum from the specific to the global (or general); (2) that scales can be constructed which represent different levels of generality, within the same content area; (3) that such scales…

The suppressor variable, a variable wholly uncorrelated with a criterion, but which nevertheless improves prediction because of its relationship with a predictor, is critically examined. For a suppressor so defined, formal identities are shown with part, partial, and multiple correlational procedures. It is demonstrated that if maximum prediction…

This article (1) examines the role of idiographic theory in contemporary personality assessment and behavioral prediction methodology, (2) reviews critically empirical studies designed to evaluate the idiographic theory of individual differences in predictability, and (3) presents new data on conclusions that have been advanced toward an…

A survey of recent literature was undertaken to locate validity studies of paper-and-pencil tests which met the following criteria: (1) Studies were conducted in a business or industrial (i.e. non-education, non-military) setting; (2) Separate statistics were available for blacks and whites; (3) Race was not confounded with some outside variable…

Just as urban ecologists have shown that social behavior such as delinquency is related to spatial patterns, educational achievement should logically be related to socio-spatial patterns. Accordingly, the hypothesis of the present study is that school neighborhoods can be ecologically grouped so as to enhance the prediction of achievement. The…
