Multivariate Analysis Versus Multiple Univariate Analyses

Abstract

The argument for preceding multiple ANOVAs with a MANOVA to control for Type I error is challenged. Several situations are discussed in which multiple ANOVAS might be conducted.  Three reasons for considering a multivariate analysis are discussed: to identify outcome variable system constructs, to select variable subsets, and to determine variable relative worth.
