Webb6 juli 2024 · Next we determine a ‘critical value’ of U with which to compare our calculated test statistic, which we can do using a reference table of critical values and using our sample sizes (n=7 in both groups) and two-sided level of significance (α=0.05). Webb22 dec. 2024 · Effect sizes can be categorized into small, medium, or large according to Cohen’s criteria. Cohen’s criteria for small, medium, and large effects differ based on the effect size measurement used. Cohen’s d can take on any number between 0 and infinity, while Pearson’s r ranges between -1 and 1.
