From 2012 to 2018, CollegeBoard released seven consecutive AP Statistics exams. On those exams, there was not one question about non-linear data. Thus it is with good reason that most of us have relegated this topic to the bottom of our priority list. But with the advent of all the new resources at AP Classroom, I wanted to teach this topic, very briefly, when I taught regression. Thus I developed the attached lesson. Its goal is simple: introduce this topic with enough depth so that students can answer AP questions about this topic.
Enjoy! As always, I welcome your feedback.
