Analysis of Covariance: A Proposed Algorithm.

Frigon, Jean-Yves; Laurencelle, Louis

Educational and Psychological Measurement, v53 n1 p1-18 Spr 1993

The statistical power of analysis of covariance (ANCOVA) and its advantages over simple analysis of variance are examined in some experimental situations, and an algorithm is proposed for its proper application. In nonrandomized experiments, an ANCOVA is generally not a good approach. (SLD)
