WORTH 100 POINTS PLZ HELP The number of pets owned by eight classmates is shown below: 1, 3, 2, 2, 1, 3, 3, 1 Part A: What is the mean of the data? Show your work. (4 points) Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work. (6 points)

mean = 2

MAD = 3/4

Step-by-step 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|
