Read each question carefully and provide your answers in the space provided. Show all your work for calculations.

1. Define Mean Absolute Deviation (MAD) in your own words and explain what it measures.

2. The first step in calculating MAD is to find the   of the data set.

3. After finding the deviations from the mean, we take the   value of each deviation.

4. A smaller MAD indicates that the data points are generally   to the mean.

5. Calculate the Mean Absolute Deviation for the following data set: {10, 15, 12, 18, 20}.

6. Which of the following data sets would likely have the largest Mean Absolute Deviation?

a

{5, 6, 5, 7, 6}

b

{1, 10, 20, 30, 40}

c

{100, 101, 100, 102, 101}

d

{15, 15, 15, 15, 15}

7. Mean Absolute Deviation is always a non-negative value.

T

True

F

False

8. Two students, Alex and Ben, took 5 quizzes. Alex's scores were {80, 85, 90, 75, 90}. Ben's scores were {70, 95, 80, 85, 90}. Calculate the MAD for each student's scores and determine who had more consistent scores.
