Calculate the mean deviation from the mean for the following data :
57, 64, 43, 67, 49, 59, 44, 47, 61, 59
Given, Numbers of observations are given.
To Find: Calculate the Mean Deviation.
Formula Used: Mean Deviation =
Explanation: Here, Observations 57, 64, 43, 67, 49, 59, 44, 47, 61, 59 are Given.
Deviation |d| = |x-Mean|
Mean =
Mean of the Given Observations =
And, The number of observations is 10
Now, The Mean Deviation is
Mean Deviation =
Mean Deviation of the given Observations =
Hence, The Mean Deviation is 7.4
