Using it's concept, the mean absolute deviation of the data-set is of 2 sundaes.
What is the mean absolute deviation of a data-set?
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
The mean for this problem is:
(4 + 6 + 2 + 4)/4 = 4
Hence the MAD is:
(|4-4| + |6-4| + |2-4| + |4-4|)/4 = 1
Since each unit represents 2 sundaes, the mean absolute deviation is of 2 sundaes.
