Question

Explain the steps in calculating the mean absolute
deviation of a set of data.

Answer 1

Sample Answer: First, find the mean of the data set by averaging. Next, find the absolute deviations for each data point. That is, find the distance each point is from the mean. Then find the mean of the absolute deviations.

Which did you include in your explanation? Check all that apply.

Find the mean of the set of data.

Find the absolute deviations for each point.

Absolute deviation is a data point’s distance from the data set’s mean.

Find the mean of the absolute deviations.

Answer 2

Explanation:

First, add each number in the set of data. Then, divide the sum by the count of numbers in the data set.

example:

DATA SET:

5 4 7 6

MEAN STEP 1:

5 + 4 + 7 + 6 = 22

MEAN STEP 2:

Since there are four numbers in the data set, divide 22 by four.
