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