This year my math department focused on student engagement in our professional development meetings. My AP Statistics colleagues (Doug Shuman and Alexandra Brennan) and I developed this activity for the 𝜒² unit as a result and the three of us implemented it in our classrooms. Here's a little information about this two-part activity. Even though our students faked their data, it was a real success!
In my classroom, I use a variety of nontraditional mechanisms to assess my students. Some of the assessments have some interesting benefits, including virtually wiping out student cheating... by letting them cheat.
