Hedges' g

Hedges' g is a statistical measure used to compare the difference between two groups' average scores, like treatment vs. control. It adjusts for differences in sample sizes and variability, providing a standardized effect size. Think of it as a way to quantify how much one group differs from another in a consistent, interpretable manner. A larger Hedges' g indicates a bigger difference, while a smaller or near-zero value suggests little to no difference. It's especially useful in research to understand the practical significance of experimental results across different studies.
