Explanation:
Purpose: discover if daily exercise would help or not on the ability to solve math problems.
We need a large sample to have various people with different cognitive abilities.
The experimental group will have to exercise at least 15 minutes a day, and the control group will go on with their normal lives, we will have to put a math exam with the same difficulty at the end and at the beginning of the experiment to see if the experimental group and the control group perform significantly better.
The data would be the two different math tests and the amount of exercise that both groups do daily.
If the experiment group performs significantly better than the control group in the final results we could support that the exercise helps perform better at math.
