What is the purpose of the dependent variable in an experiment?

The dependent variable in an experiment serves as the outcome that is measured to assess the impact of changes made to the independent variable. When an experiment is conducted, researchers manipulate the independent variable, which is considered the cause, and observe the resulting changes in the dependent variable, which represents the effect. This relationship is fundamental to the scientific method, as it allows scientists to analyze how altering one factor can lead to different results.

In this context, the dependent variable provides valuable data that helps validate or reject the hypothesis being tested. Its significance lies in its role as the measurable outcome influenced by the conditions set by the independent variable, giving researchers insights into the dynamics of the experiment.
