Answer:

mean = 2

MAD = 3/4

Explanation:

1, 3, 2, 2, 1, 3, 3, 1

To find the mean, add up all the numbers and then divide by the number of terms

(1+ 3+ 2+ 2+ 1+ 3+ 3+ 1)/8 = 16/8 = 2

To find the mean absolute deviation

subtract the mean and the number and then take the absolute value, add them together and then divide by the number of terms

|(1-2)| +|(3-2)| +| 2-2| +|2-2|+|1-2| +|3-2|+|3-2| +|1-2|
