The dependent variable is the variable that changes in response to the independent variable, in this case, the exposure to violence on television. The level of aggressiveness at the end of the month is the dependent variable as it will change depending on whether the children were exposed to violence on television or not. Therefore, option A is the correct choice. Option B is incorrect because the amount of violence watched is the independent variable, which is being manipulated by the researchers. Option C is incorrect because it includes both the independent and dependent variables. Option D is incorrect because the children are not the dependent variable, but are the participants or subjects of the experiment.
