Calculate the mea

Answer :

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation.


Formula Used: Mean Deviation =


Explanation: Here, Observations 3011, 2780, 3020, 2354, 3541, 4150, 5000 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


2354, 2780, 3011, 3020, 3541, 4150, 5000


Therefore, The Median = 3020


Deviation |d| = |x-Median|


Now, The Mean Deviation is



Mean Deviation =


Hence, The Mean Deviation is 649.42
