Quizplus · Accepted Answer

The independent variable is the variable that is deliberately changed or manipulated by the researcher to see its effect on the dependent variable. In an experiment, the independent variable varies for the experimental group, but it remains the same or constant for the control group. Therefore, the correct answer is D, independent variable. The extraneous variable is a variable that can affect the results of the experiment but is not deliberately manipulated by the researcher. The control variable is a variable that is kept constant in both the experimental and control groups. The dependent variable is the variable that is being measured or observed to see if it changes in response to the independent variable.
