The Discriminating Power of Items that Measure More than One Dimension.

PDF pending restoration

Reckase, Mark D. – 1986

The work presented in this paper defined conceptually the concepts of multidimensional discrimination and information, derived mathematical expressions for the concepts for a particular multidimensional item response theory (IRT) model, and applied the concepts to actual test data. Multidimensional discrimination was defined as a function of the…

Analysis of Contingency Tables Involving Multiple-Response Data.

Carlson, James E.; Spray, Judith A. – 1986

This paper discussed methods currently under study for use with multiple-response data. Besides using Bonferroni inequality methods to control type one error rate over a set of inferences involving multiple response data, a recently proposed methodology of plotting the p-values resulting from multiple significance tests was explored. Proficiency…
