To calculate the mean absolute deviation (MAD), Leon first needs to find the absolute difference between each data point and the mean, then calculate the mean of those absolute differences.
Given data: 18, 24, 15, 9, 10
Mean = 15.2
Absolute differences:
|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
Calculating the mean absolute deviation:
(2.8 + 8.8 + 0.2 + 6.2 + 5.2) / 5 = 4.6
Therefore, the final equation for determining the mean absolute deviation would be:
MAD = 4.6
