Traditional Dimensionality versus Essential Dimensionality
ARTICLE

Journal of Educational Measurement Volume 28, Number 2, ISSN 0022-0655

Abstract

A statistical method, W. F. Stout's statistical test of essential unidimensionality (1990), for exploring the lack of unidimensionality in test data was studied using Monte Carlo simulations. The statistical procedure is a hypothesis test of whether the essential dimensionality is one or exceeds one, regardless of the traditional dimensionality. (SLD)
