Read each question carefully and show all your work. Calculate the Mean Absolute Deviation (MAD) for each data set where required and interpret its meaning.
1. In your own words, explain what Mean Absolute Deviation (MAD) measures and why it is a useful statistic.
2. The first step in calculating MAD is to find the of the data set.
3. MAD is a measure of variability.
4. Calculate the Mean Absolute Deviation for the following data set: {10, 12, 15, 18, 20}.
5. A student scored the following on their last five math tests: 75, 80, 85, 90, 95. Calculate the MAD for these scores.
6. If a data set has a MAD of 0, what does this imply about the data points?
All data points are different.
All data points are identical.
The mean of the data set is 0.
The data set has no outliers.
7. A higher Mean Absolute Deviation indicates that the data points are more spread out from the mean.
True
False
8. Consider two data sets: Set A: {5, 6, 7, 8, 9} Set B: {1, 5, 7, 9, 13} Without calculating, which set do you expect to have a higher Mean Absolute Deviation and why?
