Question 6 • Concepts in Probability and Statistics
Mean absolute deviation measures how far data values typically lie from the mean, so a wider spread suggests a greater MAD. Choice D spans from tick 1 to tick 10, with its box stretching from tick 2 to tick 9; the other plots have much shorter boxes and ranges. Therefore, D represents the greatest spread and is the best choice for the greatest mean absolute deviation.
