Set 1: 0, 4.5, 5, 5, 8.5, 11.5, 12.5, 17.5, 20, 20.5, 24, 26, 27.5 Set 2: 0.5, 4, 6.5, 21, 21.5, 24, 24.5, 27.5, 29.5, 33.5, 34.5 Both sets measure the same thing. Which answer choice correctly compares variability using mean absolute deviation (MAD)? Round MAD to the nearest tenth if you calculate it.
