Data collected by the Federal Trade Commission from the Educational Testing Service (1975 to 1977) and two commercial coaching schools in the New York metropolitan area are used in an observational study to test the hypothesis that commercial coaching can improve performance on the Scholastic Aptitude Test. (Author/PN)

Considers forecasts of A-Level results made by teachers for candidates for a Management Sciences university course. The forecasting mechanism is found to be accurate but some conclusions which are important for university selection can be made. (Author)

A test of basic knowledge in statistics was developed to predict performance in a graduate level statistics course for psychology students. Test scores plus GRE scores were used to predict final exam performance in a graduate statistics course. The devised test predicted performance moderately well. (RD)

Exercise stress testing provides information on the aerobic capacity, heart rate, and blood pressure responses to graded exercises of a healthy adult. The reliability of exercise tests as a diagnostic procedure is discussed in relation to sensitivity and specificity and predictive accuracy. (JN)

The purpose of this study was to investigate how individuals use information about a target student's past academic performance to evaluate that performance and to predict future performance. The importance of observers' reactions to nonlinear and linear performance patterns is discussed. (Author/GK)

Defines the concept of relative effectiveness, describes the construction of an instrument to identify relatively effective children, reports experiments to validate the concept and method of measurement, and discusses the relevance of these to issues in educational procedures, predictions of situational behavior, and other concepts that have been…

Investigated whether delinquency is the result of a rational decision. The Subjective Expected Utility (SEU) model from decision theory was used with male juvenile offenders (N=45) as the model of the decision process. Results showed that the SEU model predicted 62.7 percent of the subjects' decisions. (Author/RC)

A multivariate investigation of the dynamics of cumulative achievement studied the influence of course grades, personality traits, environmental variables, and previous performance. The latter was the best single predictor of performance. (CJ)

Uses the Delphi Technique to examine the attitudes of superintendents and professors of educational administration on the problems that will confront administrators in the next five years. (IRT)

Taylor and Russell produced a set of tables which gives the proportion of successful cases when a given cutoff score or a predictor variable and the correlation between the predictor variable and the criterion are known. This paper extends this procedure to the case where parameters are not known. (Author/JKS)

Gender differences in resistance to stress are not rooted in recognition of coercive elements, but in differences in responding to coercive elements. Type As are particularly sensitive to threats to personal control. The critical difference may be in the frequency rather than the intensity of the stress. (JAC)

Correlations between the two screening tests and between the screening and criterion measures were inconsistent with prediction rates based on classificational screening test scores. On the basis of correlational validity coefficients, relationships between measures in this study would have been overestimated. (Author/SBH)

The Minnesota Child Development Inventory (MCDI) was used to describe the developmental status of 59 children before the start of kindergarten. A number of variables from the MCDI were highly correlated with this continuum of difficulty in mastering reading, with parental report of the child's general development and knowledge of letters and…

Sources of error in body composition assessment by laboratory and field methods can be found in hydrostatic weighing, residual air volume, skinfolds, and circumferences. Statistical analysis can and should be used in the measurement of body composition. (CJ)

Presents a newly developed projective technique that utilizes criminal fantasy to help predict crime. Statistical significance regarding the difference in number of judged pathological stories for the two groups was reached for all cards that were designed to elicit sexual fantasy. (Author)
