The table shows the heights of 5 students in inches.What is the mean absolute deviation for these numbers?
59,71, 68, 75,67
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.
