Which of the following describes a dependent variable?

The correct answer highlights that a dependent variable is one that is measured in an experiment to determine the effects of manipulating another variable, known as the independent variable. In research, the dependent variable reflects the outcomes or responses that are evaluated to see how they change as a result of the independent variable manipulation. For example, in a study investigating the effect of different amounts of sunlight on plant growth, the growth of the plants would be the dependent variable since it is measured to assess the impact of the sunlight exposure (independent variable).

Understanding this concept is crucial for designing experiments and interpreting their results. By recognizing the dependent variable, researchers can focus on how changes in the independent variable influence the results, leading to conclusions about the relationships between variables.
