The distinction between independent and dependent variables is crucial for understanding experimental design and statistical analysis in psychology and other scientific fields. The independent variable is the factor that researchers manipulate to observe its effects. By changing the independent variable, researchers can investigate how it influences another variable, known as the dependent variable.

The dependent variable, on the other hand, is what researchers measure in the experiment. It reflects the outcome or effect that occurs as a result of changes made to the independent variable. This structured relationship allows researchers to establish cause-and-effect dynamics in their studies.

In this context, the correct choice emphasizes that the independent variable is the one being actively changed, while the dependent variable is the outcome that is assessed in response to that manipulation. Understanding this distinction is essential for anyone studying experimental psychology and research methodologies.
