To find the mean absolute deviation, we first need to find the mean of the numbers.
Step 1: Find the mean of the numbers.
Mean = (59 + 71 + 68 + 75 + 67)/5 = (340)/5 = 68
Step 2: Find the absolute deviations.
|59 - 68| = 9
|71 - 68| = 3
|68 - 68| = 0
|75 - 68| = 7
|67 - 68| = 1
Step 3: Find the mean of the absolute deviations.
Mean absolute deviation = (9 + 3 + 0 + 7 + 1)/5 = 20/5 = 4
So the mean absolute deviation of the numbers is 4.
