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.

Your data is missing, but i have answered this question previously.to find the mean, you add all the numbers together and then divide by the number of numbers (6).4 + 12 + 20 + 24 + 32 + 40 =   132132/6 = 22to find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)18 + 10 + 2 + 2 + 10 + 18 = 6060/6 = 10the mean absolute deviation is 10.the correct answer is that stefano should have divided by 6 when finding the mean absolute deviation.
