AP Statistics Assignment for Week of 5/26

This Week’s Assignment

Watch these three videos:

  1. Two-Sample T-test Example 1
  2. Two-Sample T-test Example 2
  3. Matched Pairs T-test

Take notes as needed and revise your response to the ACT Investigate Task by Friday, May 29 at 2:00 pm. If you are just editing the existing Google Document that you have already submitted, you do not need to submit the document a second time. Otherwise, use the typical file naming guidelines

Chi-Square Tests

Due to the closure and the lost class time that involved, we were forced to skip the last unit of the course. Ms. Seifert and I have decided this content is still important for you to see, so we’re going to use the last two weeks of class to go back and discuss one more category of inference: the Chi-Square Test.

Ms. Seifert has created some more videos to watch, so please take the time to check them out here:

  1. Chi-Square Test for Goodness of Fit
  2. Chi-Square Test for Homogeneity
  3. Chi-Square Test for Independence
  4. (Optional): Stats Medic Summary of Chi-Square Tests

You may also want to check out the Desmos lesson we did in class on the 28th as a guided introduction to Goodness of Fit tests in particular. We didn’t get the chance to work on the second example (attached earlobes and tongue-rolling) together, but if you want to enter your responses and get some feedback, let me know and I can leave comments on your work. Make sure you sign in to your Google Account on Desmos, otherwise you won’t be able to access your responses again!

By Friday, June 5 at 2:00, please log into AP Classroom and take the Chi-square “Quiz” that is posted. The system should give you your score automatically after you complete the assignment, and if you have any questions about it, please sign up for Office Hours so we can chat!

This work is optional and not completing it will not impact your grade for the course.

AP Exam Model Responses

AP exam questions have been released to teachers, but there are too many versions of the exam to write the model responses that I promised. Instead, if you’d like to review your responses with me, you can sign up for an Office Hours session and we can chat. For security reasons, I won’t be able to reveal the exact text of the questions you saw, but I’ll answer any questions you might have about your response to the best of my ability.

AP Statistics Assignment for Week of 4/27

UPDATE (4/29): The deadline for your task response has been changed. Your work is now due on Monday, 5/4 at 2:00 pm


UPDATE (4/28): When you are writing your response, please use an equation editor to create any formulas that you are referring to. There are several options, but I recommend an add-on called MathType. Instructions for installing and use can be found in this short video.


At this point, we have finished all new content and you’ve had opportunities to put much of what you’ve learned into practice. This week, you’ll do so again with a graded Investigative Task assignment.

Your assignment this week is simple: Complete the Chapter 22-24 Investigative Task by Monday 5/4 at 2:00 pm. This task asks you to analyze and draw conclusions about ACT scores for a group of students, and first part of this task involves gathering a sample of students. Find the full roster of scores here: ACT Task Data.

Recall the usual submission guidelines: Your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us) by 2:00 on Friday. Please name your file appropriately; it should have the format “LastName.FirstName.Ch22-24InvTask”.  For example, mine would be Kirk.Benjamin.Ch22-24InvTask”. When you are writing your response, please use an equation editor to create any formulas that you are referring to. There are several options, but I recommend an add-on called MathType. Instructions for installing and use can be found in this short video.


New AP Exam Information

CollegeBoard VP of Advanced Placement Trevor Packer will be hosting another webinar for teachers on Tuesday evening. I hope to get some more information about the content of the exam, how the online portal will work, and what you’ll need to know before you log on.


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, 4/30 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. Come by and say hello and ask some questions. I look forward to seeing you!

Planned agenda:

  • Timed free response problem (15 minutes)
  • Discussion of AP-style rubric grading (5 minutes)
  • Questions about Investigate Task
  • Information about AP Stats exam

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: Understanding the AP exam.
  • 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.

AP Statistics Assignment for 3/6

We will have an in-class Investigative Task tomorrow. It will prioritize the content of Chapter 20, but you should expect part of this will be completing a confidence interval or hypothesis test procedure from a previous chapter. Be advised that this will be a closed notes/closed book task. You may refer to your “Way of the Hypothesis Test” sheets for this task.

From the exercises in Chapter 20, please complete 15, 19, 27, 31, 35

AP Statistics Assignment for 11/20, plus Test Warning

Finish reading Chapter 12. Pay particular attention to the sections on matching, blinding, and placebos, as these were important topics we didn’t enough time to discuss in class.

Your next Personal Progress Check has been assigned. Log into AP Classroom and complete the Unit 3 MCQ Part B PPC by Monday, November 25

On Monday, we will have our Unit 3 Test. We will spend Friday reviewing, and in preparation for that you should take a look at the review problems for Unit 3: pages 331-336, exercises 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41. You’ll get answers and supplemental review on Friday.

Tomorrow, Thursday the 21st, you’ll have an in class investigative task for Chapter 12, where you will be asked to design an experiment for a scenario. Unlike other tasks, this will be closed notes/closed book, and your hand-written response will be due at the end of the period.

AP Statistics Assignment for 11/6

AP Statistics Assignment for 10/10

We will be referring again to the Tale of Two Cities activity from last week. Period 1 can find your data here, and period 7 students can find your data here.

Finish reading Chapter 7 (Pages 192-197). Also, watch this video from APStatsGuy, which gives a great explanation for how r^2, the Coefficient of Determination, is interpreted.

From pages 208-209, do 24a, 33, 34, and 48

Also: read over the Chapter 7 Investigative Task. As with previous tasks, you’ll have the opportunity to ask questions about this in class tomorrow and will have the weekend to complete your response in a Google Document, to be shared with me once you are done. A heads up: your response will be due by 10:00am on Monday, October 14 (not Tuesday when we get back!)

AP Statistics Assignment for 9/20

Read the What If? and What Can Go Wrong sections from Chapter 4 (pages 93-95).

Over the weekend, write your response for the Chapter 4 Investigative Task (Auto Safety). As before, you may use your textbook and notes to help you write your response, and you may use the Internet to access Google Docs and Stapplet or whatever other graph-making tools you want to use, but you may use no other resources other than those. Do not go online looking for more information, and definitely no working with other students on this assignment.

Your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us) by the start of class on Monday, the 23rd. Please name your file appropriately; it should have the format “LastName.FirstName.Ch4InvTask”.  For example, mine would be “Kirk.Benjamin.Ch4InvTask“.

If you would like to rewatch or explore the data of the documentary from in class, you can find it here: The Fallen of WWII. Try the interactive version to explore the data more thoroughly.

AP Statistics Assignment for 9/13

Over the weekend, write your response for the Chapter 2 Investigative Task (Race and the Death Penalty). As noted in the document, you may use your textbook and notes to help you write your response, and you may use the Internet to access Google Docs and Stapplet or whatever other graph-making tools you want to use, but you may use no other resources other than those. Do not go online looking for more information, and definitely no working with other students on this assignment.

Your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us) by the start of class on Monday, the 16th. Please name your file appropriately; it should have the format “LastName.FirstName.Ch2InvTask”.  For example, mine would be “Kirk.Benjamin.Ch2InvTask“.

Because some folks have asked, you can find instructions on taking screenshots using a Chromebook here. I recommend the Ctrl+Shift+Window Switch shortcut to take a screenshot of only the particular items you want to use.

AP Statistics Assignment for 9/12

Your main priority tonight is to familiarize yourself with your first Investigative Task about Race and the Death PenaltyDo not start yet. Just read it over and come in with any questions you might have to understand the task.

See here for some additional reading about Simpson’s Paradox.  You should also take a look at questions 41 and 42 from page 42 of the text.
