Evaluated the extent to which the Graduate Record Examinations General Test measures the same constructs for older test takers that it does for younger examinees. Results suggest that the convergent validity of the test is similar across the age groups, but discriminant validity is somewhat different for older examinees. (Author/RWB)

THE STUDY EMPIRICALLY DETERMINED THE EFFECTS OF NONNORMALITY UPON SOME SAMPLING DISTRIBUTIONS OF THE PRODUCT MOMENT CORRELATION COEFFICIENT (PMCC). SAMPLING DISTRIBUTIONS OF THE PMCC WERE OBTAINED BY DRAWING NUMEROUS SAMPLES FROM CONTROL AND EXPERIMENTAL POPULATIONS HAVING VARIOUS DEGREES OF NONNORMALITY AND BY CALCULATING CORRELATION COEFFICIENTS…

The Stanford-Binet (Fourth Edition) (S-B:FE) and Kaufman Assessment Battery for Children (K-ABC) were administered in counterbalanced order to a sample of 30 non-handicapped, preschool children (13 males and 17 females). The children ranged in age from 3 years 11 months to 6 years 2 months, with a mean age of 4 years 11 months. Mean scores on the…

Factor-analyzed the WISC-R, PIAT, and WRAT scores of 183 male, learning disabled students. Findings suggest intelligence and achievement are composed of similar traits and skills. Therefore, comparison of individual achievement test scores with traditional Verbal, Performance, or Full Scale intelligence for learning disabled children may not be…

The standardization of the Escala de Inteligencia Wechsler para Adultos (EIWA) and the original Wechsler Adult Intelligence Scale (WAIS) were subjected to principal components analysis to examine their comparability for 616 EIWA subjects and 800 WAIS subjects. Similarity of factor structures of both scales is supported. (SLD)

This paper presents results of a LISREL factor analysis on data from the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wechsler Intelligence Scale for Children-Chinese Revised (WISC-CR) (published in 1986) for children ages 6.5 to 16.5 years, using a standardization sample of 200 children (100 males and 100 females) at each of…

The Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet: Fourth Edition (S-B:FE) were administered in counterbalanced order to a sample of 20 middle-class preschool children (11 males and 9 females) attending the Early Childhood Preschool Center located in a suburban area of a large midwestern city. Subjects' mean age was 4…

Cognitive differences between 987 LD children and 178 EH children in public schools on a psychoeducational assessment battery were studied, and differences in factor structure were investigated. Caution is suggested in interpreting the results of multivariate statistical analyses, which indicated heterogeneity in the matrices of LD and EH…
