Find the mean deviation from the median for the following data :

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation

Formula Used: Mean Deviation =

Explanation.

Here we have to calculate the mean deviation from the median. So,

N = 20

SO, The median Corresponding to 10 is 12

Mean Deviation =

Mean deviation for given data

Hence, The Mean Deviation is 1.25.
