Question

Find the Mean Absolute Deviation: 5, 11, 2, 7, 16. The Mean is 8.2.

  1. 3.2
  2. 2.8
  3. 1.2
  4. 4.2

hintHint:

Algorithm for calculating MAD:
  1. To find the mean absolute deviation of the data, start by finding the mean of the data set.
  2. Find the sum of the data values and divide the sum by the number of data values.
  3. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
  4. Find the sum of the absolute values of the differences.
  5. 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
