by Texas Instruments

Updated on December 12, 2014

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.
