AP Statistics Assignment for Week of 4/21

This week, we’re going to try and finish the last bit of curriculum needed to start reviewing in earnest for the AP exam. The last topic is the remaining significance tests: The One-Sample T-Test, Two-Sample T-Test, and Matched Pairs T-Test.

Complete by Thursday at 10:00 am

  • Required: Watch Videos 7.1, 7.2, and 7.3 in Unit 7: Significance Tests on Stats Medic.
    • Optional: Watch videos 7.4, 7.5, and 7.6. The first two videos cover forms of statistical inference that have been omitted from the AP exam, and so we will be skipping those. Video 7.6 is some more about Type I/II errors and Power. You’re welcome to watch it.
    • Please click the red “Complete Step” button
  • Required: Read the notes that I have left with each video (click theNotes Icon (Stats Medic)icon) for additional information, answers to anticipated questions, and tips about using the calculator
  • Optional: Ask a question, answer somebody else’s question, or answer one of my “discussion question” prompts
  • Optional: Finish reading Chapter 22 (pages 586-597 about the One Sample t-Test) and Chapter 23 (pages 614-624 about the Two Sample t-Test), as well as Chapter 24 (pages 634-648, about the Matched Pairs t-Test and Interval). Work on some of the odd numbered exercises in each chapter and check your answers in the back of the book.
    • I highly recommend reading through Chapter 24, since the Stats Medic videos are a little light on this topic
  • Optional: Watch the Hypothesis Tests for Means video from CollegeBoard’s live AP Statistics streams.
  • Optional (strongly recommended): Complete 2015 Free Response Question #4 (as posted in Stats Medic) and score it using the video
    • This question is from the actual AP exam in 2017, and is similar to what you could expect to see on our exam this year. I very strongly recommend you write an answer as thoroughly as you would if it appeared on the actual exam, then score yourself using the rubric video. You can expect that your AP exam questions will be scored in a similar way.
    • If you do work on it, spend no more than 15 minutes completing it. Time yourself!
  • Required: Complete the Unit 7 Practice Multiple Choice in Stats Medic
    • You may skip questions 6, 7, 10, 16, and 17. You’re welcome to try them, but they deal primarily with the Chi-Squared and Regression inference procedures that we are omitting this year.
    • Your grade for this will be based on your completion, not your correctness.

 

Office Hours

In addition to our regularly scheduled Zoom meeting on Thursday at 10 (see below), I have set aside some time where I will be available for anybody who wants to drop in and talk:

  • Office Hours Block 1: Wednesdays from 2:00 pm to 4:00 pm
  • Office Hours Block 2: Fridays from 10:00 am to 12:00 pm
  • Or by appointment
  • Please register for an office hours session by entering your name in my Office Hours Registration Form here.

Thursday Zoom Meeting

On Thursday, 4/23 at 10:00 am, I will host a virtual classroom, again using Zoom (click here for the Chrome app if you’re using your Chromebooks, otherwise I recommend the downloaded version). I’ll post the link to join here and send it out by email when that goes live. I will be starting precisely at 10:00, so please log in early! Come by and say hello and ask some questions. I look forward to seeing you!

Planned agenda:

  • Welcome/check in
  • Questions about 1-sample t-tests, 2-sample t-tests, and/or matched pairs t-tests
  • Questions about Unit 7 Practice Multiple Choice Questions
  • Collaborative work on Unit 7 Practice Free Response Question + Scoring

After Thursday Zoom Meeting, due by Monday, April 27 at 2:00 pm

  • Required: Complete the Unit 7 Practice Free Response Question in Stats Medic
    • If you attend the Thursday Zoom Meeting, my plan is to start this together.
    • You can write out your answers on a separate piece of paper, take a picture of it, and email to me.
    • Or, you can type out your response in a Google document and share it with me when you’re done.
  • Required: Log into AP Classroom and complete the Unit 7 Progress Check MCQ Part B and Unit 7 Progress Check MCQ Part C
    • Your grade for this will be based on your completion, not your correctness.
    • I’ve unlocked all Progress Checks for both Units 6 and 7. You’re welcome to try any/all of them.
    • Be aware that Unit 6 and Unit 7 of AP Classroom lines up closer with Units 5 and 6 of our textbook than with Units 6 and 7 of Stats Medic.

Ongoing additional work

  • PREVIOUS ASSIGNMENTS: Find past assignments by clicking the AP Statistics Assignment link above. I’m not checking in on these assignments as often any more, so if you do complete them now and you want me to take a look, send me an email and let me know.
  • AP VIDEO STREAMS: I highly recommend you watch the Statistics AP Live! videos run on YouTube every day from 2:00 to 2:45 pm (see this page for the full schedule for all courses). This week’s topics: Probability.
  • OTHER STATS MEDIC UNITS: I encourage you to review Units 1-4 in Stats Medic as well. I do not currently have plans to assign any content from these units, but there is very useful review to be found there, and I’m happy to answer any questions you may have about that content. Just send me an email!
  • ONLINE MATH PRACTICE: 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!
  • EXAM UPDATES: Keep an eye on CollegeBoard’s Coronavirus page for AP courses for more information about how our (and all) exam will look. The majority of you stated you plan to take whatever test CollegeBoard puts together, and the rest said you’d wait and see what they come up with for their plan.
