Quizplus · Accepted Answer

The independent variable is the variable that is being manipulated by the researcher, which in this case is the amount of sugar consumption by the participants. The restlessness of the participants is the dependent variable, which is being measured as a result of the manipulation of the independent variable. The group membership (first or second group) is simply a way of organizing the participants and is not the independent variable.
