To compare the mean GPA of all freshmen with the mean GPA of all sophomores, we need to use independent sampling with quantitative data. Independent sampling is used when we want to compare two separate groups, in this case freshmen and sophomores. Additionally, we are comparing their mean GPAs, which is a quantitative variable. Therefore, the best choice for this test is independent sampling with quantitative data.
