Treatment Groups

Groups in an experiment that receive the experimental treatment or intervention, whose outcomes are compared to a control group.

Factorial Design

A type of experimental design that allows researchers to examine the effects of two or more variables simultaneously by changing them together instead of independently.

Independent Variables

Factors deliberately manipulated by researchers to investigate their effect on dependent variables.

Dependent Variable

In research, it is the variable being tested and measured for change, to see how it responds to variations in the independent variable.
