Question

Multiple Choice
Kim works in the undergraduate advising office and has noticed that students frequently report have more academic difficultly during their first year or college than during their later years. She finds this curious, especially since coursework in later years tends to be more demanding. Her co-worker, Kirk, points out that while freshman classes may be less demanding, students have less one-on-one instruction and students are still acclimating to college during their first year. To test whether students perform differently during their freshmen and senior years, Kim and Kirk want to compare students' first-year GPAs to their fourth-year GPAs. To reduce error, they will compare the same students at two different time periods. Which t-test should they use to test for this difference?

○ Dependent samples t-test
○ Independent samples t-test
○ or Single sample t-test
