The term independent variable refers to what is being manipulated in an experiment to observe its effects on other variables. In a research context, the independent variable is the factor that is deliberately changed or controlled to test its impact on the dependent variable, which is what is being measured or observed. By manipulating the independent variable, researchers can establish cause-and-effect relationships and understand how changes in one aspect of the study can influence others.

For example, if a study is examining the effect of a new teaching method on student performance, the teaching method would be the independent variable, as it is the factor that is varied to see how it impacts student outcomes. This clear distinction is vital in experimental research, as it allows for systematic investigation of hypotheses.

In contrast, the other terms relate to different aspects of the research process. What is being observed refers specifically to the dependent variable, what remains constant refers to controlled variables, and what is measured for outcomes correlates with the results tied to the dependent variable. Understanding the role of the independent variable is crucial for grasping the overall experimental design and the logic behind hypothesis testing in psychology.
