Dependent+Variable+Hint

The dependent variable in an experiment is the one aspect of the experiment that is measured for change to see if it has a relationship to the independent variable. CAUTION: There are two possible answers to this question, depending on how Alex designs his experiment. I will accept either if you offer a valid reason why you feel it is a correct answer.

Ask yourself what Alex will have to measure in order to collect data that will help him answer his question.
