Abstract
The intercorrelations among the 12 subtests of the WISC-R were analyzed for each of the 11 age groups in the standardization sample, using the principal-factor method. Both two- and three-factor solutions were obtained for each age group, using the maxplane method, and the stability of the two solutions from one age group to another was assessed by calculating coefficients of congruence. The two-factor solution proved somewhat more stable, but the difference was relatively small and some may actually prefer the three-factor solution.Keywords
