# Calculate the mean deviation about the median of the following frequency distribution :

Answer :

**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,

Here, N =50

Then, N/2 =

SO, The median Corresponding to 25 is 13

N = 50

Mean Deviation =

Mean deviation for given data =

**Hence, The mean Deviation is 2.72.**
