title: Procedures for Estimating Magnitude of Effects.
abstract: A review is provided of methods that estimate the magnitude of effects within experimental designs. Intraclass correlation type procedures are appropriate with any ANOVA model. Friedman's rmand Cohen's power analysis apply to many non-ANOVA type situations, but only to the Fixed Effects ANOVA design. The Gaito utility procedure has two advantages over other intraclass correlation type measures: the coefficients sum to unity (or to 100%), and coefficients for error components are obtained.
