To find the mean score for each class, we need to sum the scores and then divide by the number of students (10 in each class).
**Class 1 Scores:**
75, 80, 84, 79, 92, 86, 88, 86, 86, 90
Sum of Class 1 Scores:
75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90 = 879
Mean for Class 1:
Mean = Total Sum / Number of Students
Mean = 879 / 10 = 87.9
**Class 2 Scores:**
83, 85, 91, 93, 72, 85, 76, 80, 82, 89
Sum of Class 2 Scores:
83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89 = 885
Mean for Class 2:
Mean = Total Sum / Number of Students
Mean = 885 / 10 = 88.5
**Final Results:**
The mean score for Class 1 is **87.9**. The mean score for Class 2 is **88.5**. Based on the mean, Class **2** generally performed better on the math test.
**Class 1 Scores:**
75, 80, 84, 79, 92, 86, 88, 86, 86, 90
Sum of Class 1 Scores:
75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90 = 879
Mean for Class 1:
Mean = Total Sum / Number of Students
Mean = 879 / 10 = 87.9
**Class 2 Scores:**
83, 85, 91, 93, 72, 85, 76, 80, 82, 89
Sum of Class 2 Scores:
83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89 = 885
Mean for Class 2:
Mean = Total Sum / Number of Students
Mean = 885 / 10 = 88.5
**Final Results:**
The mean score for Class 1 is **87.9**. The mean score for Class 2 is **88.5**. Based on the mean, Class **2** generally performed better on the math test.
