Stefano calculated the mean absolute deviation for the data set 32, 4, 12, 40, 20, and 24. His work is shown below. Step 1: Find the mean. mean = StartFraction 32 + 4 + 12 + 40 + 20 + 24 Over 6 EndFraction = 22 Step 2: Find each absolute deviation. 10, 18, 10, 18, 2, 2 Step 3: Find the mean absolute deviation. M A D = StartFraction 10 + 18 + 10 + 18 + 2 + 2 Over 4 EndFraction = 15 What is Stefano’s error? Stefano should have divided by 5 when finding the mean. Stefano found the absolute deviation of 20 incorrectly. Stefano should have divided by 6 when finding the mean absolute deviation. Stefano did not find the correct value for the mean.
