Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Students are asked to assess the validity of an inference regarding two distributions given their box plots.
Students are asked to use the mean and the mean absolute deviation (MAD) to compare two distributions.
Student Resources
ProblemSolving Task
In this task, students are able to conjecture about the differences and similarities in the two groups from a strictly visual perspective and then support their comparisons with appropriate measures of center and variability. This will reinforce that much can be gleaned simply from visual comparison of appropriate graphs, particularly those of similar scale.
Type: ProblemSolving Task
Virtual Manipulatives
Users select a data set or enter their own data to generate a box plot.
Type: Virtual Manipulative
Using an interactive applet, students can compare and contrast properties of measures of central tendency, specifically the influence of changes in data values on the mean and median. As students change the data values by dragging the red points to the left or right, the interactive figure dynamically adjusts the mean and median of the new data set.
