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 = 21
SO, The median Corresponding to 10.5 is 27
Mean Deviation =
Mean deviation for given data =
Hence, The Mean Deviation is 4.80.
