Mean deviation about mean (grouped data - discrete) | Statistics | Grade 11 | Math | Khan Academy

In this video, we'll learn how to calculate the mean deviation about the mean for grouped discrete data. We begin by working through an example, showing how to calculate the mean. Then, we find the absolute deviations from this mean, multiply them by their respective frequencies, sum these products, and finally compute the mean deviation about the mean. We'll also outline the step-by-step method for this calculation. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
