Calculate the mea

Class 11th RD Sharma - Mathematics 32. Statistics

Answer :

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation from mean.

Formula Used:

Explanation: Here, Observations 4, 7, 8, 9, 10, 12, 13, 17 are Given.

Deviation |d| = |x-Mean|

Mean =

Mean of the Given Observations =

And, The number of observations is 8.

Now, The Mean Deviation is

Mean Deviation =

Mean Deviation of the given Observations =

Hence, The Mean Deviation is 3
