A mediating variable (or mediator) explains the process through which two variables are related, while a moderating variable (or moderator) affects the strength and direction of that relationship. Including mediators and moderators in your research helps you go beyond studying a simple relationship ...
The explanation involves some concepts that haven't been introduced at this point but it can still be worthwhile to discuss these types of variables. In general, a given variable may be said to function as a mediator to the extend that it accounts for the relation between the predictor and ...
Moderator variables tend to express the causal relationships between variables while the mediator variable simply extenuates the relationship of variables in a conceptual model. The evaluation found that there are indeed significant differences in the two variables in question. If statistical analysts fail...
The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations. In this article, we attempt to distinguish between the properties of moderator and mediator variables at a number of levels. First, we seek to make theoris... R M,Baro...

Assumptions Causal assumption:When you do not randomize the x variable, you must assume causation. The influencer can reverse the effect of causation if you do not presume the causation between x and y. Causal relationship:The mediator and independent , in principal, should not be related. No ...

The indirect effect of self-efficacy (as a mediator) on the relationship between PHLC (as a predictor) and SWLS (as a dependent variable) was confirmed by bootstrapping. The index of moderation mediation equals .21, boot SE = 0.10, with 95% bootstrapping CI ranges between 0.01 and 0.41...
The PROCESS macro uses ordinary least squares analysis to predict continuous variables (absolute handgrip strength) and with bootstrapping (10,000 bootstrapped samples) to determine the moderated influences25. The Johnson-Neyman approach was applied to test statistically-significant interactions and ...
