Quizplus · Accepted Answer

The statistic d, often referred to in contexts like Cohen's d, measures the effect size or the degree of separation between two population means in terms of standard deviation. It quantifies the difference between the sampled population and the null hypothesis population, rather than providing probabilities, sizes, or definitive conclusions about population differences.
