Explanation:
In a study, the independent variable is the variable that isn't changed by the other variables during the experimental procedure. On the other hand, the dependent variable is the variable being tested/measured during the experiment (in this case, children's food choice), and therefore this variable is 'dependent' on the independent variable. Finally, the control group is the group where the independent variable is not manipulated, i.e., the group where participants do not receive the experimental treatment. A control group enables the establishment of causal-effects relationships by isolating the effects of the independent variable.
