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).
- 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.
Let’s use data displays to find associations.
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.
- I can create relative frequency tables, bar graphs, and segmented bar graphs from frequency tables to find associations among variables.
