WebWe usually analyze these tables with a categorical statistical test. There are a few options, depending on the sample size and the design, but common ones are Chi-Square test of independence or homogeneity, or a Fisher’s exact test. And while that test gives you a p-value, it doesn’t give you a good effect size statistic. Cohen’s W is the effect size measure of choice for 1. the chi-square independence testand 2. the chi-square goodness-of-fit test. Basic rules of thumb for Cohen’s W8are 1. small effect: w = 0.10; 2. medium effect: w = 0.30; 3. large effect: w = 0.50. Cohen’s W is computed as W=∑i=1m(Poi−Pei)2Pei where 1. … See more For an overview of effect size measures, please consult this Googlesheet shown below.
