How is a dependent variable typically also referred to in research methodologies?

In research methodologies, a dependent variable is often referred to as an outcome variable because it represents the effect or response that is measured in an experiment or study as a result of changes to the independent variable(s). The dependent variable reflects the results of the research hypothesis and helps illustrate the relationship between the variables being studied.

For instance, if researchers are assessing the impact of a new therapy on patient outcomes, the improvement in patients' health status (measured by specific indicators) would be the dependent or outcome variable. This terminology emphasizes the dependency of the outcome on the variations applied to the independent variables, which are manipulated or altered during the research.

In contrast, alternative terms like predictor variable, constant, and confounding variable relate to different aspects of research design and analysis, but they do not capture the role that the dependent (outcome) variable plays within an experiment.
