Question
Find the Mean Absolute Deviation: 5, 11, 2, 7, 16. The Mean is 8.2.
- 3.2
- 2.8
- 1.2
- 4.2
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: 4.2
Step 1 of 2:
Given the dataset, 5, 11, 2, 7, 16
The mean is given by 8.2
Step 2 of 2:
MAD =
= 4.2
So, the MAD is 4.2
Final Answer:
The right choice is-- d. 4.2
