Who tends to carry the heaviest backpacks, boys or girls? What grade level shows the most variability in the weight of the backpacks they carry? We will use the drag and drop tools (tables, graphs, and a ruler) found in TinkerPlots Dynamic Data Exploration software to develop the concept of the mean absolute deviation, as required in grades 6 and 7 by the Common Core.
