Calculate the mean deviation from the mean for the following data :

57, 64, 43, 67, 49, 59, 44, 47, 61, 59

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation.


Formula Used: Mean Deviation =


Explanation: Here, Observations 57, 64, 43, 67, 49, 59, 44, 47, 61, 59 are Given.


Deviation |d| = |x-Mean|


Mean =


Mean of the Given Observations =


And, The number of observations is 10


Now, The Mean Deviation is



Mean Deviation =


Mean Deviation of the given Observations =


Hence, The Mean Deviation is 7.4
