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
