Calculate the mean deviation about the median of the following observation :
3011, 2780, 3020, 2354, 3541, 4150, 5000
Given, Numbers of observations are given.
To Find: Calculate the Mean Deviation.
Formula Used: Mean Deviation =
Explanation: Here, Observations 3011, 2780, 3020, 2354, 3541, 4150, 5000 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
2354, 2780, 3011, 3020, 3541, 4150, 5000
Therefore, The Median = 3020
Deviation |d| = |x-Median|
Now, The Mean Deviation is
Mean Deviation =
Hence, The Mean Deviation is 649.42
