Lesson objective: Describe data using measures of center, spread, and shape.

This lesson helps to build fluency with describing data sets. Box plots, dot plots, and histograms are used here because they support visualization of center, spread, and shape. This work develops students' understanding that measures of center and spread can be used to describe a data set.

Students engage in Mathematical Practice 2 (reason abstractly and quantitativitely) as they describe a data set and as they analyze the measures of center and variability, along with data displays.
