To find the mean score for each class, we need to sum the scores and then divide by the number of students.
**Class 1 Scores:**
75, 80, 84, 79, 92, 86, 88, 86, 86, 90
Calculating the mean:
Sum of Class 1 Scores = 75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90 = 869
Mean for Class 1 = Total sum / Number of students = 869 / 10 = 86.9
**Class 2 Scores:**
83, 85, 91, 93, 72, 85, 76, 80, 82, 89
Calculating the mean:
Sum of Class 2 Scores = 83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89 = 885
Mean for Class 2 = Total sum / Number of students = 885 / 10 = 88.5
Now we can summarize the results:
- Mean for Class 1 = 86.9
- Mean for Class 2 = 88.5
Based on the mean, Class 2 generally performed better on the math test.
So the final answers are:
The mean score for Class 1 is **86.9**. 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
Calculating the mean:
Sum of Class 1 Scores = 75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90 = 869
Mean for Class 1 = Total sum / Number of students = 869 / 10 = 86.9
**Class 2 Scores:**
83, 85, 91, 93, 72, 85, 76, 80, 82, 89
Calculating the mean:
Sum of Class 2 Scores = 83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89 = 885
Mean for Class 2 = Total sum / Number of students = 885 / 10 = 88.5
Now we can summarize the results:
- Mean for Class 1 = 86.9
- Mean for Class 2 = 88.5
Based on the mean, Class 2 generally performed better on the math test.
So the final answers are:
The mean score for Class 1 is **86.9**. The mean score for Class 2 is **88.5**. Based on the mean, Class **2** generally performed better on the math test.
