Growth curve modeling provides a general framework for analyzing longitudinal data from social, behavioral, and educational sciences. Bayesian methods have been used to estimate growth curve models, in which priors need to be specified for unknown parameters. For the covariance parameter matrix, the inverse Wishart prior is most commonly used due…

Presents table for determining relative rarity of quotient discrepancies on Wechsler Intelligence Scale for Children-Revised (WISC-R) to be used with children at higher Intelligence Quotient levels. Theoretically derived table has been confirmed through empirical observation of WISC-R standardization sample. Suggests table use should reduce…

Investigated Kaufman's procedures for determining intersubtest scatter on the Wechsler Intelligence Scale for Children-Revised by means of Sattler's revised tables for determining significant subtest fluctuations. Results indicated that Sattler's revised tables yielded more conservative estimates of subtest scatter than those originally reported…

Investigated the relationship between subtest scatter on the Wechsler Intelligence Scale for Children and higher intellectual potential as indicated by subsequent reexamination and grouping of children. Results indicated that scatter on the initial examinations is a poor indicator of the presence of higher intellectual potential. (Author/RC)

In the fall of 1992, Wechsler Intelligence Scale for Children-III (WISC-III) scores from 330 referred children in an urban midwestern school district were analyzed to provide information regarding score distribution of the referred population and of the ethnic and gender profiles within the referred group, and to examine changes from prior…
