To find the mean score of each sample, we add up all the scores and divide by the number of students in each class.

For Class 1:
(75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 870 / 10 = 87

The mean score for Class 1 is 87.

For Class 2:
(83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 846 / 10 = 84.6

The mean score for Class 2 is 84.6.

Comparing the mean scores, Class 1 generally performed better on the math test.
