From η2 to ω2: Adopt a Better Measure of Effect.

Abstract

A cursory review of relevant research works published in the Journal of Nursing Education suggests that our community may unnecessarily rely on η² when reporting results of their ANOVA models. Although η² is convenient, the statistic possesses many limitations that warrant our community adopting a wider set of effect size statistics and practices to promote a valid science of nursing education. We specifically call attention in this article to ω². [J Nurs Educ. 2023;62(9):532-533.].
