This Instructional Activity is a part of the Lesson 11, Unit 8, Grade 7. In this activity, students continue to review the meaning of mean and mean absolute deviation as well as practice using the method they were shown in the previous activity to compare multiple groups based on their means and measure of variability. Students begin by matching information about a set of data to its dot plot and calculating the mean and mean absolute deviation for the remaining dot plots, then they compare the data sets pairwise using the mean and MAD values. In the discussion, students are introduced to a way to add extra information to dot plots to visualize the general rule given in the previous activity.
