Building Another Type of Two-Way Table

This Instructional Activity is a part of the Lesson 9, Unit 6, Grade 8. In this activity, students should use an informal understanding of association to think about whether one is present in the data based on the relative frequency table. Keep students in groups of 2-3. After an introduction to relative frequency tables, allow students 3 minutes quiet work time followed by partner discussion and whole-class discussion. Display the table for all to see. Ask students, "Based on this data, who is more likely to watch the news daily: someone who is younger than 18 or someone who is 18 or older?"
