Find the Mean Absolute Deviation: (MAD)
10, 9, 3, 8, 10.
- 3
- 5
- 1
- 2
Hint:
Algorithm for calculating MAD:
- To find the mean absolute deviation of the data, start by finding the mean of the data set.
- Find the sum of the data values, and divide the sum by the number of data values.
- Find the absolute value of the difference between each data value and the mean: |data value – mean|.
- Find the sum of the absolute values of the differences.
- Divide the sum of the absolute values of the differences by the number of data values.
The correct answer is: 2
Step 1 of 2:
The mean is 
= 8.
Step 2 of 2:
MAD = 
= 
= 
So, the MAD is 2.
Final Answer:
The right choice is-- d. 2
