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.].
