Definitions:

Interaction Effect

In statistics, the effect that exists when two or more variables combine to affect the outcome of a dependent variable in a way that cannot be simply added.

Main Effect

In experimental design, a main effect is the direct impact of an individual independent variable on a dependent variable, ignoring the effects of other variables.

Simple Effect

The effect of one factor at a specific level of another factor in a factorial design experiment.

Factorial Research

A methodological approach in experiments where researchers study the effects of two or more independent variables across multiple levels.
