Question

Which data set has a wider spread? Why? Set A: {9, 11, 24, 11, 4, 20, 16, 7, 18, 15, 28, 6} Set B: {9, 12, 15, 3, 21, 24, 5, 9, 16, 21} Set A has a wider spread because it has more data values than Set B. Set A has a wider spread because its mean is greater. Set A has a wider spread because its range is greater. Set B has a wider spread because its median is greater. Set B has a wider spread because it is bimodal. NextReset

Answer 1

Data Set A:
Lowest Value is 4
Highest Value is 28
Range = 28 - 4 = 24

Data Set B:
Lowest Value is 3
Highest Value is 24
Range = 24 - 3 = 21

Data Set A has bigger range than Data Set B, hence it has a wider range

Answer: Set A has a wider spread because its range is greater.
