# Analyzing Center and Spread Using Stacked Box Plots Activity

## Overview

This activity encourages students to analyze center and spread of the number of chocolate chips in 5 different brands of chocolate chip cookies.

# Observe/Compare

Allow students to make observations about comparing and contrasting the different box plots.  Obviously, we want students to comment on similarities and differences of the centers and spreads.  The attached hand-out can be used in class if you would like for students to record their observations on paper.  Teachers may decide to just have students simply discuss their observation with a partner.

# Share

If students were working individully on Task 1, then in Task 2 students should share their observations with a partner.  Then add to their list of observations on the hand-out.

# Interpret/Apply

This step should push students to make connections between the box plots and the context of the chocolate chips.  Hopefully, students will consider the size of the chips, size of the cookies, and other practical differences that may account for the differences in distributions.

# Assessment

Students will make a copy of the google doc and complete the assessment.  Students will then share that with you or you can print it for them and make paper copies for them to turn in to you.
