Read each question carefully and follow the instructions to calculate the Mean Absolute Deviation (MAD) for the given data sets. Show all your work.

1. Calculate the Mean Absolute Deviation (MAD) for the following data set: {10, 15, 20, 25, 30}

2. Find the MAD for the data set representing the number of points scored by a basketball team in their last 5 games: {85, 90, 78, 92, 80}

3. The Mean Absolute Deviation measures the average   between each data point and the   of the data set.

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

5. A data set with a MAD of 0 means all data points are identical.
