test.

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

Mean score for Class 1:
(75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 856 / 10 = 85.6

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

Based on the mean score, Class 1 generally performed better on the math test compared to Class 2.
