Why Multivariate Methods Are Usually Vital in Research: Some Basic Concepts.
The present paper suggests that multivariate methods ought to be used more frequently in behavioral research and explores the potential consequences of failing to use multivariate methods when these methods are appropriate. The paper explores in detail two reasons why multivariate methods are usually vital. The first is that they limit the inflation of Type I error rates, and the second is that multivariate methods best honor the reality to which the researcher is purportedly trying to generalize. Three general analytic premises provide a framework for the discussion: (1) all statistical analyses are correlational; (2) the OVA (analysis of variance and covariance) analyses do not in and of themselves yield the capacity to make causal inferences; and (3) statistical significance tests do not evaluate the probability (p) that results will replicate. Eleven tables illustrate some analyses. (Contains 51 references.) (Author/SLD)
