I'm new to Hypothesis testing. I can't really think of how to answer this -

Five students take a test one year and another test the next year. Their overall grades(in %) are given below for the test-1 and test-2. Which statistical procedure (e.g. t-test) would be most appropriate to claim that the students overall course grades are similar in both tests? Assume normality requirements hold.

If anyone knows the answer, kindly explain.

  • $\begingroup$ So the question is which statistical procedure to use, but the possible answers are just some numbers? $\endgroup$ Aug 31, 2023 at 12:23
  • $\begingroup$ yes exactly my confusion. I struggled to understand it too.. @user2974951 $\endgroup$ Aug 31, 2023 at 13:01
  • $\begingroup$ Set aside the multiple guess answers for a moment. How would you approach the problem? When you do it that way, do you get a number near any of the possible answers? $\endgroup$

1 Answer 1


You may apply paired t-test to test your hypothesis: the students overall course grades are the same in both tests.
