Quizplus · Accepted Answer

Independent variables are the variables that are manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. Therefore, option A is correct. Option B is incorrect because the values of independent variables need to change in different conditions of an experiment. Option C is incorrect because independent variables are also known as predictor variables, not criterion variables. Option D is incorrect because the change in the values of independent variables does not depend on the value of dependent variables. Option E is incorrect because independent variables have a significant impact on the outcome of the experiment.
