This lesson is optional because it revisits content that is below grade-level. If the pre-unit diagnostic assessment indicates that students know the representations well, this lesson may be safely skipped.

This lesson serves as a brief review of the meaning of dot plots, histograms, and box plots and how they are created.

Students calculate values for the five-number summary and use those values to create dot plots. They also compare different representations of the same data using histograms with different intervals, dot plots, and box plots.

When students identify the information displayed by different graphical representations, they are building knowledge about when to use appropriate tools (MP5), which will help them make choices about how to represent data. Students make use of structure (MP7) to connect visual representations of data sets and to reason abstractly and quantitatively (MP2) by interpreting values in the given contexts.
