3/28 Update: As we look to the next two weeks, I’d like your feedback on how to approach instruction. Please complete this short survey about the content and method of this instruction.
3/27 Update: I made a video debrief of the Desmos lessons below that you can take a look at here.
Also, all AP Statistics students have been granted access to IXL, an online math practice tool. There are skill practice modules for math content all the way from Kindergarten through Calculus, and there’s even some decent AP Statistics content.
You will have to log in via Clever (instructions are here), click the IXL button on the page that loads, and then navigate to the Pre Calculus section. Any of the modules in sections X: Probability, Y: Probability Distributions, or Z: Statistics would be worthwhile practice for you!
3/24 Update: CollegeBoard has released a daily schedule of their live webcasts, which will start on Wednesday the 25th. The full list/archive of course topics can be found here; the first AP Statistics topic will be for Chi-Squared Tests for Goodness of Fit, a topic from late in the course that we likely will not get to in our own work (and will not appear on your exam later).
Our first review topic will be about the power of a hypothesis test (which, you’ll recall, we defined to be the probability of a test correctly detecting a false null hypothesis.
This lesson will take place over a few parts on Desmos. For each part, you’ll log in at student.desmos.com and enter the given class code. Make sure you click the Sign in with Google button so that your results are saved. If you’re one of the first few people who complete the activity, be sure to log back in later and see what other people have said!
- Chapter 1: Calculating power – Class code 2BE4Y4
- Chapter 2: Influencing/changing power – Class code QRSQK7
- Chapter 3: Connecting power to Type I/Type II errors – Class code BCMF65
- Note: I made some errors in the coding of slides for Chapter 3 here, so I had to upload a new version. Those of you who completed the old version can still find it here.
If you have questions, post them here or send me an email. On Wednesday, 3/25 at 10:00 am, I will host a virtual office hour using Google Meet. I’ll post the link here and send it out by email when that goes live. Come by and say hello, ask some questions, or just chat. I look forward to seeing you!
Collegeboard has released some information about how AP exams will be impacted. From that update:
- Traditional face-to-face exam administrations will not take place. Students will take a 45-minute online free-response exam at home. This exam will be composed entirely of free response questions
- Some students may want to take the exam sooner rather than later, while the content is still fresh. Other students may want more time to practice. For each AP subject, there will be 2 different testing dates.
All exams will cover a reduced version of the course curriculum, as detailed on the page above. For AP Statistics, this means Units 1-7 from the Collegeboard curriculum, which correspond to Units 1-6 of our textbook.
More information about what each exam will actually look like will be available on April 3.
At least until Spring Break, I will not be attempting any new instruction from Unit 6. I encourage you to search for videos online, or to check out the instructional videos that the AP Program is putting together. If you have your textbook, read through Chapters 22, 23, and 24 and work on some of the odd-numbered problems. While I won’t be formally teaching any of that content yet, I’ll be more than happy to answer any questions you might have.
