Answer 1

Comparing the centers of the data sets, the median for Data Set A is equal to the median for Data Set B.

Comparing the variability of the data sets, the range for Data Set A is 17 (29-12) and the range for Data Set B is 21 (34-13), so the range for Data Set B is greater.

Furthermore, the mean for Data Set A is 19 and the mean for Data Set B is 19.83, so the mean for Data Set B is slightly greater than the mean for Data Set A.
