This opening-day activity was shared with me at a PD several years ago, the original (I think) version is located here - thanks to NCSSM for sharing! The stem of the activity is derived from the 2007 AP Statistics Exam Question 5. I did not really change the original format, but I like this activity for many reasons: It gets the students talking about graphs and numerical summaries from the beginning Students are able to jump in with simulations and collecting data We create our first dotplot as a class- they see that they already know a lot about this course We find and interpret a p-value... even though they don't know it yet! The class can see a computer created simulation and we get to compare it to ours My kiddos get used to working in a collaborate manor Thanks for reading! ~ssb
