WebA effect size measure attempts to assess the size of the effect in a way that is not influenced heavily by the sample size. Cohen's d is computed by using the following formula: d = … Web10. Quick question: I've seen Cohen's d calculated two different ways for a dependent samples t-test (e.g., within-samples design testing the efficacy of a medication with pre/post timepoints). Using the standard deviation of the change score in the denominator of the equation for Cohen's d. Using the standard deviation of the pretest score in ...
