Interpreting Effect Sizes
A way to judge whether a measured relationship (like test score vs. job performance) is practically meaningful for hiring decisions.
"If a test correlates with performance, how big does that correlation need to be before I change hiring practice?"
Effect size quantifies the strength of the relationship between a predictor (e.g., a skills test) and an outcome (e.g., job performance); practical significance asks whether that strength is large enough to matter for real hiring decisions.
