The effect of a moderating variable is characterized
statistically as an interaction
; that is, a categorical (e.g., sex, ethnicity, class) or quantitative (e.g., level of reward) variable that affects the direction and/or strength of the relation between dependent and independent variables. …
How do you interpret a moderation effect?
Moderation effects are difficult to interpret
without a graph
. It helps to see what is the effect of the independent value at different values of the moderator. If the independent variable is categorical, we measure its effect through mean differences, and those differences are easiest to see with plots of the means.
What exactly is an interaction moderation effect?
1. What exactly is an interaction/moderation effect?
When a third variable (X
1
) and an independent variable (X
2
) affect the dependent variable (Y) simultaneously
.
When a third variable (X
1
) reduces the effect of an independent variable (X
2
) on the dependent variable (Y)

a way to check whether that third variable influences the strength or direction of the relationship between an independent and dependent variable

How do you explain moderation?
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 do you calculate moderation?
The most common measure of effect size in tests of moderation is
f
2
(Aiken & West, 2001) which equals the unique variance explained by the interaction term divided by sum of the error and interaction variances. When X and M are dichotomies f
2
equals the d
2
/4 where d is the d difference measure described above.
