what is the (MAD) of the data 2,2,5
The MAD (Mean Absolute Deviation) of the data 2, 2, 5 is:
First, find the mean: (2 + 2 + 5) / 3 = 3
Next, find the absolute deviation of each number from the mean:
- |2 - 3| = 1
- |2 - 3| = 1
- |5 - 3| = 2
Then, find the mean of these absolute deviations:
(1 + 1 + 2) / 3 = 4/3
So the MAD of the data is 4/3 or approximately 1.33.
