Abstract
Previous research has touted the advantages of the one-way ANOVA over the repeated-measures ANOVA when missingness is high and correlations between measurement points are low (e.g., Callahan, Horta, & Sperling, 2021). The present study showed that a multilevel modeling approach maintained greater statistical power than both types of ANOVAs.
