This video explains how to calculate the mean deviation about the median for grouped discrete data. We'll walk through an example, starting with finding cumulative frequencies and determining the median value. Then, we'll calculate the absolute deviations of each observation from the median, find their products with the corresponding frequencies, sum these products, and finally, divide by the total number of observations to get the mean deviation about the median. The general steps for this calculation will also be outlined. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
