What does the dependent variable represent in an experiment?

In an experiment, the dependent variable is fundamental as it represents the measurement outcome that is affected by the manipulation of the independent variable. This means that researchers will observe changes in the dependent variable to assess the impact of whatever they have altered as the independent variable. For instance, if an experiment examines the effect of different amounts of sunlight on plant growth, the height of the plants would be the dependent variable, as it is what the researchers measure to see how it is influenced by the varying sunlight levels.

Understanding this concept is crucial because it helps establish cause-and-effect relationships within the experimental framework. By clearly identifying the dependent variable, researchers can analyze the data collected and draw conclusions about how modifications to the independent variable have brought about changes in the measured outcomes.
