On the relationship between the JCCES and the Reynolds Intellectual Assessment Verbal Scale (Part 4)

Here are the results of a Hierarchical Ascendant Classification (HAC) analysis for the T-scores of the JCCES subtests and the RIAS verbal subtests.

This cluster analysis used the Ward's method based on Chebyshev's distance. As shown in Figure 1, the dendogram revealed two distinct groups into the principal one: (1) a group with emphasis on reasoning related abilities in which we could see a subpart gathering verbal reasoning measures, (2) and another that links the tasks of verbal knowledge.
