Students work to describe distributions of data using terms such as “symmetric,” “skewed,” “uniform,” “bimodal,” and “bell-shaped.”

An optional lesson is included to remind students of prior learning about measures of center and measures of variation so that those terms can be included in distribution descriptions. Even if the optional lesson is skipped, consider creating a display about the measures...

The final section of this unit is a lesson where students have the opportunity to apply their thinking from throughout the unit. As this is a short section followed by an End-of-Unit Assessment, there are no section goals or checkpoint questions.

In this section, students are introduced to additional tools to analyze data such as standard deviation and outliers. They finish the section by using all of these tools to compare similar data sets.

Note that in this unit, all standard deviations refer to the population standard deviation () calculation rather than the sample standard deviation ().

In this optional section students are introduced to using spreadsheets to create basic formulas and interpret results. It is assumed that students know nothing about spreadsheets. If students are proficient at using spreadsheets as computation tools, this sequence of lessons can be safely skipped. This technology is useful for interpreting data in this unit and is also used to examine...

In this section, students continue to build community by collecting data from their classmates, classifying the different kinds of data they might collect, and creating displays of the information that they collected.

The optional second lesson gives students a chance to practice creating dot plots, histograms, and box plots using given data before attempting to do the same with the...
