Prediction of success in a special program often guides program participant selection and treatment. If the statistical analysis used to develop such predictions is based on the special selectivity built into the program, the predictions can be misleading and the validation tests uninformative. Federal district court pretrial release data is used…

Data from surveys of university students that utilized the Approaches to Studying inventory were analyzed to test the hypothesis that a curvilinear relationship exists between learning strategies and academic grades. However, none of the non-linear regression models investigated improved significantly on the explanatory power provided by the…

Double cross-validation of a test battery against multiple criterion variables found the first general factor accounts for most criterion variance in cross-validated regression weights. Small contributions are made by mechanical/technical and psychomotor factors. It appears a common general factor plays the major role in validity for a range of…

Applied a logistic model to predict elderly patients' risk for discharge to nursing homes following hospitalization. Age was the only consistently strong predictor in the individualized models developed for each of four areas. (Author/JAC)

Twelve teachers estimated achievement test performance, basic intellectual ability, and academic motivation of each of their pupils. Standardized reading achievement and intelligence tests were administered to the pupils. Analyses revealed a high level of accuracy for achievement judgments when assessed against test scores. Pupil gender did not…

Reports on the steps undertaken and the discoveries made by the English department of Illinois State University in its development of a valid, reliable measure of student competency in freshman composition. (HOD)

Reveals that the cloze and comprehension test scores correlated at significant levels, thus supporting the predictive validity of the cloze procedure. (RB)

Statistically significant relationships were found between dropping out and occupation and between dropping out and the accuracy of the SVIB. Such relationships may influence results of follow-up studies on the validity of the SVIB. (Author)

The Federal Court decision in the Griggs case may lead to fundamental changes in test practices. (Author)

An empirical study of statistical overkill investigated the generalizability of multiple regression equations as a function of the subject/variable ratio. Data from various-sized groups of rehabilitation clients were used to develop the equations. Findings showed that equations developed on samples with less than a 10 to 1 ratio failed to…

The generation of empirically-based equations is within the grasp of most researchers in occupational education. This paper was designed to develop a sensitivity to the need for cross-validation in these circumstances. Program CROSVAL is a means of bridging the gap between the need for, and mechanization of, cross validation. (Author/DS)

In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. (Author)

Some of the procedures for developing and validating learning sequences or learning hierarchies are explored. For each of these procedures, references are provided that can be used for additional study or clarification of the procedures. (Author)

The SIT Correlates highly enough with ACT scores to be considered a valid instrument for predicting acceptance and success in college. (Authors)
