Answer:
a. Your dependent variable has two operational definitions.
Explanation:
In an experiment there are some types of variables that help the researcher to evaluate all hypotheses of his research. These variables are called dependent and independent. The independent variable is the one that represents the research element that can be measured and manipulated by the researcher. In the case of the above research, this variable is the type of activity the children were doing. On the other hand, the dependent variable is one that depends on the manipulation of the independent variable to present a response that can be evaluated by the researcher.
In the case of research, shown in the question above, the dependent variables will be the amount of time it will take a child to eat sweets and the amount of sweets eaten. For this reason, we can conclude that in this experiment the dependent variable has two operational definitions.
