What does a moderator variable do?
The term moderating variable refers to a variable that can strengthen, diminish, negate, or otherwise alter the association between independent and dependent variables. Moderating variables can also change the direction of this relationship.
What’s the difference between a mediator and a moderator?
In a mediation relationship, you can draw an arrow from an independent variable to a mediator and then from the mediator to the dependent variable. In contrast, a moderator is something that acts upon the relationship between two variables and changes its direction or strength.
What does it mean when a variable is a mediator?
A mediator is a way in which an independent variable impacts a dependent variable. It’s part of the causal pathway of an effect, and it tells you how or why an effect takes place. If something is a mediator: It’s caused by the independent variable.
How does a mediation model work in statistics?
Rather than a direct causal relationship between the independent variable and the dependent variable, a mediation model proposes that the independent variable influences the (non-observable) mediator variable, which in turn influences the dependent variable.
How does a moderator affect the relationship between variables?
A moderator influences the level, direction, or presence of a relationship between variables. It shows you for whom, when, or under what circumstances a relationship will hold. Moderators usually help you judge the external validity of your study by identifying the limitations of when the relationship between variables holds.
