WebbThe calculation of standardized mean differences (SMDs) can be helpful in interpreting data and are essential for meta-analysis. In psychology, effect sizes are very often reported as an SMD rather than raw units (though either is fine: see Caldwell and Vigotsky (2024) ). In most papers the SMD is reported as Cohen’s d 1. Webb4 feb. 2024 · The standardized (mean) difference is a measure of distance between two group means in terms of one or more variables.
