Hypothesis testing is used to look if there is any significant relationship, and we report it using a p-value. Measuring the strength of that relationship is as important, if not more and effect size is the number used to represent that strength. WebAn effect size measure summarizes the answer in a single, interpretable number. This is important because. effect sizes allow us to compare effects-both within and across studies; we need an effect size measure to estimate (1 - β) or power.
