Mean Deviation About Median Formula. This includes the median which is the n 2 th order statistic or for an even number of samples the arithmetic mean of the two middle order statistics. Co efficient of mean deviation from mean frac m d overline x co efficient of mean deviation from median frac m d m the co efficient of mean deviation from mode frac m d mode solved examples.
