Vedclass · Answer

(B) The mean deviation is defined as the sum of absolute deviations from a central value divided by the number of observations. It is a well-known mathematical property that the sum of absolute deviations $\sum |x_i - A|$ is minimized when $A$ is the median of the data set. Therefore,the mean deviation from the median is the minimum possible value compared to the mean deviation measured from any other value.
