1.
Mean of Group A = (56 + 14 + 26 + 28 + 29 + 45 + 32 + 80 + 3 + 10) / 10 = 33.3
Mean of Group B = (27 + 24 + 18 + 19 + 5 + 16 + 22 + 10 + 6 + 20) / 10 = 16.7
Difference in means = 33.3 - 16.7 = 16.6
2.
Range of Group A = 80 - 3 = 77
Range of Group B = 27 - 5 = 22
Group A has a larger range, indicating more inconsistency.
3.
For Group A, after sorting the numbers: 3, 10, 14, 26, 28, 29, 32, 45, 56, 80
Median = (28 + 29) / 2 = 28.5
For Group B, after sorting the numbers: 5, 6, 10, 16, 18, 19, 20, 22, 24, 27
Median = (18 + 19) / 2 = 18.5
Difference in medians = 28.5 - 18.5 = 10
Use this data for #1,2,3
Student Group A: 56, 14, 26, 28, 29, 45, 32, 80, 3, 10
Student Group B: 27, 24, 18, 19, 5, 16, 22, 10, 6, 20
1. Find mean of group A and B (tenth) and find their difference
2. Find range of each student group and tell which group is more inconsistent
3. Find the median of each student group, (tenth if needed) and find their difference in medians
