Effect size is a quantitative measure that describes the magnitude of the difference between two groups' means. It is often used in statistical analysis to understand the practical significance of research findings, beyond just the p-value which indicates whether the finding is statistically significant. Effect size helps to answer the question, "How big is the difference?" regardless of the sample size. Common measures of effect size include Cohen's d, Pearson's r, and odds ratios, among others.
