Factorial Research Design

A type of experiment design that involves two or more independent variables, allowing researchers to examine the effect of each variable and the interaction between them.

Main Effects

In the context of analysis of variance (ANOVA), refers to the individual impact of each independent variable on the dependent variable, disregarding interactions.

Interaction Effects

Occurs when the effect of one independent variable on the dependent variable differs according to levels of another independent variable.
