Question

Dr. Oguz counted the number of cubs in 10 tiger cub litters and then arranged the numbers from smallest to largest. The numbers of cubs in each litter were 1, 1, 2, 2, 3, 3, 3, 4, 5, and 6. The mean of these measurements is 3.
What is the mean absolute deviation?

A.
1.2

B.
1.5

C.
2

D.
12

Answer 1

The question asks us to find the mean absolute deviation ( MAD ). We know that the mean is 3. First we have to find the distance of the each value from the mean ( and ignore minus signs ). For example: 1 - 3 = | - 2 | = 2 ( absolute value ) etc. Then we have to find the mean of their distance: MAD = ( 2 + 2 + 1 + 1 + 0 + 0 + 0 + 1 + 2 + 3 ) / 10 = 12 : 10 = 1.2. Answer: The mean absolute deviation is A ) 1.2.
