Wow!  Two weeks without a post.  Of course, we’ve just been reviewing for AP and final exams and taking them, so nothing much to report, but still!

WE DID IT!  Now go enjoy your summer!

For both of you who happen to check this blog once more because you are incredibly bored on some summer afternoon, I just want to say thank you.  Thank you for the way you made AP Statistics and/or AP Seminar better than it would have been without you.  I hope that you have a great summer and hope to see you next year, whether you are still at Wheeler or are visiting back from college!

AP Stat

Yesterday, I accidently posted the free response questions twice instead of posting the questions and the scoring guidelines.  I have corrected that now.

Today we reviewed description of data and study design (the first 5 pages of the review packet).  Tomorrow, we will look at probability and do a couple of practice inference problems.

AP Seminar

Today was the AP Exam, and I hope those of you who took it aced it!!! Today we looked at the practice exam we took yesterday.

Today we went over the quiz from chapters 11-12 and worked on a full free response test for the AP Exam.  Here is a copy of the questions: 2017 Free Response Questions and here are the scoring guidelines: 2017 FRQ scoring guidelines.  Also make sure that you have the review packet: What Is Not on the Formula Sheet

AP Seminar

Today we did the practice AP (or final) exam practice packet. If you were not here, PLEASE DO THIS BEFORE THE FINAL EXAM!  Here are the questions: Practice Questions and here is the scoring rubric: Scoring Rubric.  If you are not sure how to grade your response, here are sample answers and scores: Samples and scores

Today we looked back at Type I and Type II Errors and the Power of a Test.  The worksheet is here: Who Stole the Cookie Recipe

Remember that the quiz over Chapters 11-12 is Thursday.  We will review tomorrow, but I would like for you to do the Chapter 12 review tonight so that you may come in with questions.  Also, here are some practice multiple choice problems:

Chapters 11-12 Multiple Choice Practice Problems and

Orange Book Ch 11-12 Multiple Choice

If you are having trouble with Chapter 12.2 (especially if you weren’t here yesterday), you can try this video, which tracks our powerpoint pretty well:

Regression transformation to linearity

If you are confused, please talk with me tomorrow.

AP Seminar

Another sub-30 minute class today, and we had one presentation.  More tomorrow.

Today we finished the new material for this year.  We looked at transforming curved (power and exponential functions) to achieve linearity.  That way, we can get a linear regression line, conduct an r and r squared analysis and make inferences.  To do this, we take the natural log of both x and y for a power model and for just the y for an exponential model.  If you were not here today, you may need to ask a few questions tomorrow during class, but I would still like for you to look at the notes and try the homework.  The notes are here: tps4e_ch12_12-2.  Homework is to read pages 765-771 and do problems33, 35,  37, 41, 43, 49 and 51.

AP Seminar

Today, one person presented.  That’s all we did.  After all, it was only a 20 minute class.

Homework is to read pages 696-722 and do problems 27, 33, 35, 37, 39, 45 and 51.
