Key Concepts

Independent Variable

The independent variable is the factor that researchers manipulate to observe its effect on another variable. In experimental design, this variable is considered the cause or input and is deliberately varied to test its impact on the outcome.

Dependent Variable

The dependent variable is the outcome that is measured in an experiment to see if it is affected by changes in the independent variable. It represents the effect or response, and its variation provides insight into the influence of the independent variable.
