This product includes two different activities for using two-way tables to analyze a set of data and calculate relative frequencies. This is a good practice or summative assignment for this section. Students must already know how to calculate relative frequencies.
The first two-way table activity involves surveying the class about their eye color and whether or not they wear glasses/contacts. The class can then turn the survey data into a two-way table and analyze it. In my class we did this one together, but it could also be group work or an individual practice assignment.
The second activity asks students to come up with their own research question, create a survey, give out their survey, and then analyze the data and answer their research question using their findings. This one works well as a project for more advanced students.
