Quizplus · Accepted Answer

A measure of effect size is a statistic that quantifies the strength of the relationship between variables. Statistical power refers to the probability of correctly rejecting the null hypothesis when it is indeed false, and is not a direct measure of the relationship between variables. Error variance and within-group variability refer to factors that may affect the precision and accuracy of statistical analyses, but do not specifically measure the strength of the relationship between variables.
