Conducted a Monte Carlo computer simulation of the ANOVA design to detect job differences. The design proved reasonably powerful in detecting differences. A second study used Monte Carlo methods to analyze the viability of techniques for determining job differences. Offers guidelines for selecting statistical techniques. (Author/RC)

Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…

Describes a criterion group classification scheme commonly used in conjunction with discriminant function analysis and suggests that clinicians consider membership probabilities for each criterion group of interest. Illustrates this approach using data from a study in which discriminant analysis was used to identify characteristics of problem…

New Medical College Admission Test (MCAT) scores and undergraduate academic achievement were examined for their validity in predicting the performance of two select student populations at Northwestern University Medical School. The data support the hypothesis that New MCAT scores possess substantial predictive validity. (Author/MLW)

Prekindergarten children were given a perceptual discrimination task using letterlike forms and their transformations. The magnitude of the relation to subsequent achievement in reading varied according to the difficulty of a transformation. More easily discriminated transformations were associated with higher correlations. Patterns were similar…

The relationship between elementary school children's mental ability scores and classroom performance was investigated. A strong predictive relationship between mental ability scores and classroom performance was obtained irrespective of the subjects' socioeconomic status. These findings indicate that predictions of academic performance derived…

The predictive validity of the new Medical College Admission Test as it relates to end-of-quarter examinations in anatomy, histology, physiology, biochemistry, and "ages of man" is presented. Results indicate that the Science Knowledge assessment areas of chemistry and physics and the Science Problems subtest were most useful in…

Problems in grading and evaluating English compositions are discussed. Factors include methods of marking, reliability, prediction, characteristics of markers, and handwriting. The effect of time passage on evaluation criteria was determined by comparing essays written in 1922 with new ones written on the same topic (f=fiche number). (MH)

Using grade point average and graduation-nongraduation as two separate criteria and eight predictor variables selected from doctoral applicants' folders at an Arizona university, a canonical correlation of .624 for a sample of 65 graduate students shrank to -.095 for a cross validation sample of 21 students. (CTM)

The computation, concept, and application subtests of the Stanford Achievement Tests (SAT) were administered to a student sample during grades 3, 5, and 7. The efficiency of earlier scores and Otis Lennon Mental Ability Test scores in predicting seventh-grade SAT math scores was examined and found to be weak. (SJL)

Responding to allegations about the effect of coaching on the Scholastic Aptitude Test (SAT) and its predictive validity ("Harvard Educational Review," May 1980), Jackson evaluates Slack and Porter's arguments and addresses the issues of the utility of SAT scores as admissions criteria and the alleged misrepresentation of negative…

Race and socioeconomic status predicted achievement of disadvantaged first graders on the Stanford Early School Achievement Test; equating these factors did not establish equality of achievement. Students with kindergarten experience performed similar to norms on the letters and sounds subtests, but lower on mathematics, aural comprehension, and…

Light's retention scale does not meet standards for a psychometric device for schools. Possibly because of low reliability, the total score was not found to have concurrent validity. The scale needs revision in item content to be accepted by teachers. (Author)

Play was a significant predictor of success on all three measures of achievement. Socioeconomic status and sex appeared to have little influence on the prediction of achievement. Dramatic play had the most significant impact. (Author)

Attempted to clarify the dynamics between creativity and misbehavior in the classroom by determining the extent to which creativity test scores predict identification of students by teachers and/or peers as misbehavers. Results generally failed to support that high creativity scores predict teacher identification of students as behavior problems.…
