Ms. G is a college track coach who is curious about the appropriate amount of distance training for her athletes. Ms. G decides to run an experiment. She randomly divides her runners into two groups. The first group does about 20 miles of distance training per week, and the second group does about 30 miles of distance training per week. At the end of the two weeks, all of the runners compete in a mile run, yielding the results below. Based on the center and variability of each distribution, what inferences can you draw about the
two populations? By visual inspection, which group would you expect to have a greater MAD based on the plots?
