Calculate the mea

Answer :

Given, Numbers of observations are given in two groups.

To Find: Calculate the Mean Deviation from their Median.


Formula Used: Mean Deviation =


For Group 1: Since, Median is the middle number of all the observation,


So, To Find the Median, Arrange the Income of Group 1 in Ascending order, we get


4000, 4200, 4400, 4600, 4800


Therefore, The Median = 4400


Deviation |d| = |x-Median|


Now, The Mean Deviation is



Mean Deviation =


Mean Deviation Of Group 1 =


For Group 2: Since, Median is the middle number of all the observation,


So, To Find the Median, Arrange the Income of Group 2 in Ascending order, we get


3800,4000,4200,4400,4600,4800,5800


Therefore, The Median = 4400


Deviation |d| = |x-Median|


Now, The Mean Deviation is



Mean Deviation =


Mean Deviation Of Group 2 =


Hence, The Mean Deviation of Group 1 is 240 and Group 2 is 457.14
