Middle Grades Math: Say It With a Survey

Objectives

• Students will represent bivariate categorical data with bar charts and split bar charts.
• Students will examine and describe patterns in bivariate categorical data by displaying frequencies in a two-way table.
• Students will use relative frequencies to identify a possible association between the two variables.

Vocabulary

• bivariate data
• categorical data
• split bar chart
• two-way tables

About the Lesson

This lesson involves using given bivariate and multivariate categorical data to display bar charts and construct two-way tables.
As a result, students will:

• Construct bar charts and split bar charts for categorical data.
• Build tables and two-way tables by gathering information in the charts.
• Find any patterns of association in the charts or tables.
