Mediating variable acts as an intermediate variable between independent variable and the criterion variable (dependent variable). Unless the mediating variable is present, the effect between independent variable and criterion variable will be insignificant.
The correlation between the predictor and the mediator variables, and the correlation between the mediator and criterion variables should be significant. The correlation between predictor and criterion should be reduced (to zero in the case of total mediation) after controlling the relation between the mediator and criterion variables.
Moderating variable increases or decreases the effect of an independent variable on the criterion variable (dependent variable).
In analysis of variance (ANOVA), a basic moderator effect can be represented as an interaction between an independent variable and another variable.
