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.
True
False
6. The Mean Absolute Deviation is always a positive value.
True
False
7. Two students measured the length of a table. Student A's measurements (in cm) are: {150, 152, 149, 153, 151}. Student B's measurements (in cm) are: {145, 160, 150, 155, 140}. Calculate the MAD for each student's measurements and determine who had more consistent measurements.
