# Calculate the mea

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
