Calculate the mean deviation about the median of the following observation: 3011,2780,3020,2354,3541,4150,5000

Explanation

Formula for Mean deviation is :

MD=`1/n​∑∣di​∣`

Here `d_i​=x_i​−M` where M is the median

Arrange the data in ascending order

`2354,2780,3011,3020,3541,4150,5000`

Here Median is the middle most observation.

Here ,

Median `(M)=3020` and `n=7`
