Students continue the work with bivariate data from Lesson 9. Similar to Lesson 9, this lesson uses the superpower data to address the statistical question, “Do high school males have different preferences for superhero powers than high school females?” The two-way frequency table from Lesson 9 is used to develop a relative frequency table that allows students to compare the responses of males and females. However, the statistical question is still not clearly answered.
As students complete the exercises in this lesson, they begin to see the need for conditional relative frequencies, which are introduced in Lesson 11. Students also begin to understand how conditional summaries are used to answer the statistical question.
