A Chi-Square Test for Hierarchical Dependency.
Guay, Roland B.; McCabe, George P.
The Chi-Square Test for Hierarchical Dependency (THD) is presented. The THD tests the hypothesis that all members of a population who possess a certain skill are a subset of the members who possess another skill. This hypothesis is basic to the writings of several prominent theorists, such as Gagne and Piaget. The THD is designed as an improvement over existing tests of this hypothesis, e.g., the Test of Inclusion. The model, assumptions, formula derivations, and procedures for the THD are explained. An illustrative example of an application of the THD, involving two spatial skills, is provided. (Author/CTM)
