Standardized mean of a contrast variable information


In statistics, the standardized mean of a contrast variable (SMCV or SMC), is a parameter assessing effect size. The SMCV is defined as mean divided by the standard deviation of a contrast variable.[1][2] The SMCV was first proposed for one-way ANOVA cases [2] and was then extended to multi-factor ANOVA cases .[3]
