Question
Find the MAD for the data set: 65, 90, 85, 70, 70, 95, 55
- 12.24
- 75.7
- 85.7
- 40
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: 12.24
Step 1 of 2:
Given the dataset, 65, 90, 85, 70, 70, 95, 55
The mean is = 75.714
Step 2 of 2:
MAD =
= 12.24
So, the MAD is 12.24
Final Answer:
The right choice is-- a. 12.24
