Details

This is a covariance matrix of the 11 subtests of the WAIS based on N = 300. The subtests include: comprehension, arithmetic, similarities, digit span, vocabulary, digit symbol, picture completion, block design, picture arrangement, and object assembly. These data have been used by Bentler (1972) to show the stark difference between alpha and the glb.
