I want to design an experiment to see if drinking coffee makes students score higher on tests. List 1 necessary constant.

The type of coffee

Explanation:

Different types of coffee contain different amounts of caffeine. This makes it important to use only one type of coffee

Constant is the one thing that does not change. If you are experimenting to see if they test better with coffee, you'll need to give each student the same amount of coffee throughout each trial.
