Uses and abuses of the analysis of covariance.

S V Owen1, R D Froman.   

Abstract

The analysis of covariance (ANCOVA) is a powerful analytic tool, but there continue to be abuses of the method. We review assumptions and illustrate legitimate uses of ANCOVA, and summarize statistical packages' approach to the method. Finally, we consider how ANCOVA is used in contemporary nursing research.
