The mean score for Class 1 is (75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 85.6
The mean score for Class 2 is (83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 83.6
Based on the mean, Class 1 generally performed better on the math test.
The mean score for Class 2 is (83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 83.6
