Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.
<u>Differences</u>
72-62= 10
72-73= 1
72-74= 2
72-75= -3
72-76= -4
add the absolute values...
10+1+2+3+4=20
divide by 5 because that is how many numbers in set...
