Learning Disability Subgroups Using Cluster Analysis of the WISC-R
Jeffrey H. Snow, Morris J. Cohen, W. Bruce Holliman · Journal of Psychoeducational Assessment · 1985
The WISC-R was administered to a group of learning-disabled (LD) children and the results factor-analyzed. Factor scores were derived, and these variables were clustered using the hierarchical group procedure. The results indicated six distinct subgroups. The data are discussed in terms of cognitive patterns of subgroups of LD children.
