Research: An investigation on the impact of AI towards academic writing of students at HUFLIT.

Paired sample T-test will be used because the study will be conducted into the same class. In the first semester, AI cannot be used to support academic writing. On the other hands, in the next semester, this will be applied. A comparison will be made from the results of academic writing of students and to what extent AI can assist them. We choose the same participants because we need to evaluate the impact of AI on participants before and after the test is applied.

Your answer is clear and logically structured. You correctly chose a paired samples t-test and clearly explained that the study involves the same participants measured at two different times, which is appropriate.
To improve:
-Clarify the dependent variable (e.g., writing scores, rubric-based assessment).
-Improve wording slightly (e.g., “On the other hand” → “In the following semester”).
-You could briefly mention pre-test and post-test to make the design clearer.
