To find the MAD of the data set, we first need to find the mean (average) of the data set:
Mean = (8 + 5 + 12 + 15) / 4 = 10
Next, we find the absolute deviation for each data point by subtracting the mean from each data point and taking the absolute value:
|8 - 10| = 2
|5 - 10| = 5
|12 - 10| = 2
|15 - 10| = 5
Then, we find the average of these absolute deviations, which is the MAD:
MAD = (2 + 5 + 2 + 5) / 4 = 3.5
Therefore, the mean absolute deviation of the data set is 3.5.
