What does a dependent variable represent in an experiment?

In an experiment, the dependent variable represents the outcome that researchers are interested in measuring to see how it is affected by changes in other variables. It is the variable that researchers observe and measure in response to manipulations or changes made to the independent variable. By focusing on the dependent variable, the experiment aims to gather information about relationships or effects that may arise as a result of the experimental conditions.

Understanding this concept is crucial in the context of experimental design, as it helps researchers draw conclusions about causality and the nature of the relationship between variables. The dependent variable provides the data needed to confirm or refute a hypothesis, making it central to the scientific inquiry process. Thus, the correct interpretation of the dependent variable being the focal point of measurement and analysis is fundamental in understanding how experiments are conducted and what information they yield.
