Lesson 24
Using Data Displays to Find Associations
Lesson Narrative
In this lesson, students use two-way tables, bar graphs, and segmented bar graphs to decide whether there is evidence of an association in categorical data or not (MP4).
Teacher Notes for IM 6–8 Math Accelerated
This lesson and the previous are optional. Use these lessons if students need practice working with frequency tables, bar graphs, and segmented bar graphs.
Learning Goals
Teacher Facing
- Create a two-way table and a segmented bar graph that represent relative frequencies, and interpret (orally) the frequencies in context.
- Determine (in writing) whether categorical data has a positive, negative, or no association using a relative frequency table or segmented bar graph, and justify (orally) the reasoning.
Student Facing
Let’s use data displays to find associations.
Required Materials
Required Preparation
Use the data from the previous lesson’s cool-down to build a two-way table of students’ responses. Provide access to materials for students to create their own segmented bar graphs including colored pencils and straightedges.
Learning Targets
Student Facing
- I can create relative frequency tables, bar graphs, and segmented bar graphs from frequency tables to find associations among variables.
