Effect Size, Power, and Sample Size Determination for Structured means Modeling and Mimic Approaches to between-groups Hypothesis Testing of means on a Single Latent Construct
Gregory Robert Hancock · Psychometrika · 2001
While effect size estimates, post hoc power estimates, and a priori sample size determination are becoming a routine part of univariate analyses involving measured variables (e.g., ANOVA), such measures and methods have not been articulated for analyses involving latent means. The current article presents standardized effect size measures for latent mean differences inferred from both structured means modeling and MIMIC approaches to hypothesis testing about differences among means on a single latent construct. These measures are then related to post hoc power analysis, a priori sample size determination, and a relevant measure of construct reliability.
