In this video, we explore the calculation of mean deviation about the mean for grouped continuous data. We'll work through an example where data is given in class intervals. This involves finding the mid-points of these classes, then calculating the mean, the absolute deviations from the mean, and finally the mean deviation. We will also clearly list the step-by-step procedure to follow for such problems. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
