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

Question

Philoid · Accepted 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.
