Calculate the mea

Answer :

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation.


Formula Used: Mean Deviation =


Explanation: Here, Observations 38, 70, 48, 34, 63, 42, 55, 44, 53, 47 are Given.


Since, Median is the middle number of all the observation,


So, To Find the Median, Arrange the numbers in Ascending order, we get


34, 38, 43, 44, 47, 48, 53, 55, 63, 70


Here the Number of observations are Even then the middle terms are 47 and 48.


Therefore, The Median = = 47.5


Deviation |d| = |x-Median|


And, The number of observations are 10.


Now, The Mean Deviation is



Mean Deviation =


Hence, The Mean Deviation is 8.4
