Quizplus · Accepted Answer

The independent variable is the variable that is being manipulated by the researchers, in this case, the amount of violence watched on television. Therefore, the best choice is B. The level of aggressiveness at the end of the month is the dependent variable, meaning it depends on the independent variable. Choice C is incorrect because it includes both the independent and dependent variable, and choice D is incorrect because the children are not being manipulated, but rather are the subjects of the experiment.
