The mean score for Class 1 is (75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 84.6

The mean score for Class 2 is (83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 83.6

Therefore, Class 1 generally performed better on the math test with a slightly higher mean score of 84.6 compared to Class 2's mean score of 83.6.
