Lesson objective: Connect a Venn diagram to a two-way table.

This lesson provides an opportunity for students to apply their knowledge and understanding of two-eay tables to a real-life situation. Students are asked to convert a Venn diagram to a two-way table and identify any possible associations between the variables.

Key Concept students will use:

- Examining frequencies in two-way tables and other displays of categorical data gives information about associations.

Skills students will use:

- Identifying information in a Venn diagram (Grade 5, Unit 11)
- Finding percents (Grade 6, Unit 2)
- Identifying possible associations between categorical data (Grade 8, Unit 8)

Students engage in Mathematical Practice 5 (Use appropriate tools strategically) as they convert a Venn diagram to a two-way table and identify possible associations between categorical variables.

**Key vocabulary: **

- association
- categorical data
- conditional frequency
- percent
- relative frequency
- two-way table
- Venn diagram
