A possible scenario is to examine whether students’ writing scores improve after receiving teacher feedback. The study would involve one group of students, and their writing would be scored twice: once before feedback and once after feedback. Because the data come from the same participants at two different times, I would use a paired samples t-test. This test is appropriate because it compares the mean scores of the same group across two related measurements. In this case, the goal is to see whether teacher feedback leads to a significant improvement in writing performance.
