Two data sets contain an equal number of values. The double box-and-whisker plot represents the values in the data sets. Compare the data sets using measures of center and variation. 1 - Data set A has a greater measure of center, and Data set A has a greater measure of variation.

2 - Data set A has a greater measure of center, and Data set B has a greater measure of variation.

3 - Data set B has a greater measure of center, and Data set A has a greater measure of variation.

4 - Data set B has a greater measure of center, and Data set B has a greater measure of variation.
