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, 42, 55, 63, 46, 54, 44 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, 38,42,44,46,48,54,55,63,70

Here the Number of observations are Even then Median =

Therefore, The Median = 47

Deviation |d| = |x-Median|

And, The number of observations is 10.

Now, The Mean Deviation is

Mean Deviation =

Hence, The Mean Deviation is 8.6
