Effect Size for ANOVA Designs (Quantitative Applications in the Social Sciences)

This guide lays out the computational methods for d with a variety of designs including factorial ANOVA, ANCOVA and repeated measures ANOVA; d divides the observed effect by the standard deviation of the dependent variable. Throughout, the computations are illustrated on the same data, a comprehensive set of simulated observations on air traffic controllers. The authors also raise important theoretical issues including a discussion of off-factor in arriving at effect size as well as questions of research practice.
