Students continue the analysis of the bivariate categorical data that they began in Lessons 9 and 10. Lesson 9 summarized the data in a two-way frequency table. Relative frequencies were then introduced in Lesson 10. In each case, however, the question posed about whether there is a difference in the favorite superpower responses of males and females remains unclear.
This lesson develops and interprets conditional relative frequencies to answer the statistical question posed in the previous lessons. Students familiar with two-way tables from Grade 8 move through these questions within the suggested time frame. Students not as familiar with this work may need more time to complete these exercises.
