There are two groups of 5th grade students learning math. One group in learning in-person, and the other is learning virtually. We are testing each group before the beginning of the class, and at the end of the class to see if one way of teaching math is more effective over the other.

Ho: There is no difference in theimprovement of thetest scores of those that learn virtually versus those who learn in person.

H1: there is a difference in the improvement of the test scores of those learning virtually, versus those who learn in person.

Hoping to prove that in person is more effective than virtual.

Which statistical test would be best for conducting this study? Why?
