The mean absolute deviation is calculated by finding the absolute value of the difference between each data point and the mean, then finding the mean of those absolute differences.
The data Eon collected is 18, 24, 15, 9, 10.
First, we need to calculate the absolute differences between each data point and the mean (15.2):
|18 - 15.2| = 2.8
|24 - 15.2| = 8.8
|15 - 15.2| = 0.2
|9 - 15.2| = 6.2
|10 - 15.2| = 5.2
Next, we find the mean of these absolute differences:
(2.8 + 8.8 + 0.2 + 6.2 + 5.2) / 5 = 23.2 / 5 = 4.64
Therefore, the final equation that Eon would use to determine the mean absolute deviation is:
MAD = 4.6
