Answer:
1.63
Step-by-step explanation:
first we find the average of the numbers listed...do this by adding up all the numbers, then dividing by how many numbers there are.
(5 + 7.5 + 8.25 + 8 + 9.75 + 10.25 + 11 + 10.75) / 8 = 70.5 / 8 = 8.8125
now find the distance between the average and each of ur numbers.... IGNORE ALL NEGATIVE SIGNS
5 - 8.8125 = 3.8125
7.5 - 8.8125 = 1.3125
8.25 - 8.8125 = 0.5625
8 - 8.8125 = 0.8125
9.75 - 8.8125 = 0.9375
10.25 - 8.8125 = 1.4375
11 - 8.8125 = 2.1875
10.75 - 8.8125 = 1.9375
now take the average of those numbers
(3.8125 + 1.3125 + 0.5625 + 0.8125 + 0.9375 + 1.4375 + 2.1875 + 1.9375) / 8 =
13/8 = 1.625...rounds to 1.63 <=== this is ur MAD
