11. You want to know if studying improves grades. To test this you take 50 sophomores with the same GPA (3.0) and have half of them review biology concepts using flashcards for 10 minutes a day; the other students do not (they play Pacman instead). You will compare the average test scores of the two groups.

If 25 sophomores (3.0 GPA) review biology concepts with flashcards for 10 minutes a day while 25 sophomores (3.0 GPA) play Pacman instead, then the reviewing group will have a higher test average than the Pacman group because reviewing helps improve long-term memory of facts and concepts.
