# Choose between Mann-Whitney test and Wilcoxon?

I'm practicing this test and I have a trouble with this question:

Students' scores on the mathematics test are given in the following table. The students are divided into two groups: those who are given study guide (group 1) and those who are not (group 2).

Group 1 Group 2
70 6 88 57 79 68 85 14 88 77 72 54 87 85 62 77 86 55 82 92 87 45 85 84 57 56
To test if the median of students' scores of group 1 is higher than that of group 2, which test is most appropriate between the Mann-Whitney Test or the Wilcoxon Signed-Rank test?

I believe that the best test to use is the Wilcoxon because of the paired samples but I'm not sure.

• Well my question is basically how do you know for sure if the Wilcoxon is the best test to use for this problem? I mean arent the two groups consider a pair sample? and sorry im new to this website but i would appreciate your help @gung Commented Sep 25, 2015 at 0:28
• What makes you think the data are paired? Commented Sep 25, 2015 at 1:33
