  2. Mean Absolute Deviation and Quartiles 6.7 and 6.8

  3. Vocabulary • Measure of dispersion • A description of the dispersion or the spread of the data • Range • The difference between the greatest value and least value • Deviation from the mean • Is the difference of a data value and the mean of the data set

  4. Mean absolute deviation • Is the average deviation of the data from the mean.
