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
1. Mean of Group A: (56 + 14 + 26 + 28 + 29 + 45 + 32 + 80 + 3 + 10) / 10 = 28.3
Mean of Group B: (27 + 24 + 18 + 19 + 5 + 16 + 22 + 10 + 6 + 20) / 10 = 17.7
Difference in means: 28.3 - 17.7 = 10.6
2. Range of Group A: 80 - 3 = 77
Range of Group B: 27 - 5 = 22
Group A has a larger range, so Group A is more inconsistent.
