hi friends,
i still cant differentiate the role of moderator and mediator.
As far as i could remember,
(I) one is like a TOLL where it will directly affect the DV
(II) one is like REST & RELAX area where it might or it might not affect the DV.
please help me to clarify it
thanks
The basic explanation for moderator and mediator was well explained in the seminal article by Baron and Kenny (1986).i still cant differentiate the role of moderator and mediator.

To understand the difference, read this article by Baron and Kenny.

Moderator variables are typically introduced when there is an unexpectedly weak or inconsistent relation between a predictor and a criterion variable (e.g., a relation holds in one setting but not in another, or for one subpopulation but not for another).
Mediation, on the other hand, is best done in the case of a strong relation between the predictor and the criterion variable.
