Mean Deviation About Mean Formula. For example if the mean is 5 and a number is 7 6 the distance is 2 6. M d x x n.
The mean deviation is also known as the mean absolute deviation and is defined as the mean of the absolute deviations of the observations from the suitable average which may be the arithmetic mean the median or the mode. To calculate the mean deviation for continuous frequency distribution following steps are followed. The mean is calculated for these mid points.
