Calculate the mean deviation from the mean for the following data :
4, 7, 8, 9, 10, 12, 13, 17
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
