WebAlthough the effects are highly statistically significant, the effect sizes are moderate. We typically see this pattern with larger sample sizes. Last, we shouldn't really interpret our main effects because the interaction effect is statistically significant: F (2,114) = … In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the … See more Population and sample effect sizes As in statistical estimation, the true effect size is distinguished from the observed effect size, e.g. to measure the risk of disease in a population (the population effect size) one can … See more Whether an effect size should be interpreted as small, medium, or large depends on its substantive context and its operational definition. Cohen's conventional criteria small, medium, or big are near ubiquitous across many fields, although Cohen … See more • Estimation statistics • Statistical significance • Z-factor, an alternative measure of effect size See more Further explanations • Effect Size (ES) • EffectSizeFAQ.com • EstimationStats.com Web app for generating effect-size plots.
