How would you decide whether a variable should be considered as a mediator or a moderator?
What’s the difference between a mediator and a moderator? A mediator variable explains the process through which two variables are related, while a moderator variable affects the strength and direction of that relationship.
What is a moderating relationship?
In statistics and regression analysis, moderation occurs when the relationship between two variables depends on a third variable. The third variable is referred to as the moderator variable or simply the moderator.
How is moderation used in a relationship analysis?
Moderation analysis also allows you to test for the influence of a third variable, Z, on the relationship between variables X and Y. Rather than testing a causal link between these other variables, moderation tests for when or under what conditions an effect occurs. Moderators can stength, weaken, or reverse the nature of a relationship.
When do we use mediation in a relationship?
Overall, we use mediation analyses to explain relationships. We use moderation analyses to understand what variables affect the strength and direction of a relationship. Sources.

What are the steps in mediation and moderation?
The Steps: 1. Estimate the relationship between X on Y (hours since dawn on degree of wakefulness) -Path “c” must be significantly different from 0; must have a total effect between the IV & DV
What does moderation mean in a research paper?
We work with graduate students every day and know what it takes to get your research approved. Moderation is a way to check whether that third variable influences the strength or direction of the relationship between an independent and dependent variable.
