#### More about *Cohen’s D*

Cohen’s d corresponds to a widely used measure of *effect size*, that is used as an alternative (or complement) to the processes of hypothesis testing and calculation of p-values. Hypothesis testing has been subject to criticism because the p-values that are used to estimate the significance of an effect is heavily depending upon the sample size \(n\). A 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: \[d = \frac{|\bar X – \mu|}{\sigma}\]
