Your final Investigative Task assignment can be found here. For this task, you are being asked to complete three Chi-Squared tests to answer various questions about the results of the 2016 AP Statistics exam. You will spend some time thinking about which test to use for which question in class, and you will be asked to report your decision before you start on the task.
You are permitted to change your mind about which test is used for which question, but your task response must include an explanation for why you are changing your decision. As usual, your response should be completed in a Google Document and submitted to me (email@example.com) by the beginning of class tomorrow. Please name your file appropriately. The file name should have the format “LastName.FirstName.Ch25InvTask”. For example, mine would be “Kirk.Benjamin.Ch25InvTask“.
Finish reading chapter 25 (pages 687-697)
From pages 698-702, do exercises 1, 2, 8, 24, 27, 29
Also, fair warning that you will be assigned another Investigative Task tomorrow. You’ll have time to start thinking about it in class, but tomorrow’s homework will be to complete it.
In class today, you will gather your sample for the Chapter 22 Investigative Task. The full set of data can be found here. After selecting your sample, write a brief paragraph explaining your method and submit it to me with the filename format “LastName.FirstName.Ch22TaskPlan”
In addition to the description of your sampling method plan, I want you to practice creating equations using the app EquatIO, a tool that can create clean, professional looking equations directly into you Google Document. There are some basic instructions and some sample equations to create here: Inserting Equations into Google Documents. Add these formulas to your Task Plan document above. This assignment will count as a homework grade! Submit it by the end of the day.
Update on this (for 3rd period students): Given that EquatIO seems to be having some issues loading on your Chromebooks, you do not need to include these equations in your document due by the end of the day. You must submit your sampling method, however.
You have the weekend to complete your task response. I expect to see formulas created using EquatIO. Submit your response by the start of class on Monday with the filename format “LastName.FirstName.Ch22InvTask”
Finish reading the rest of chapter 22 (pages 586-597), then do exercises 3, 31, 33, 43, 45
Your next Investigative Task will be assigned as homework over the weekend and will be submitted electronically. Please read the setup for the assignment here: Chapter 22 Investigative Task – SAT Performance (Part 1). You’ll get the data to draw your sample in class tomorrow.
From pages 537-539, do exercises 15, 19, 27, 31, 35
We will have an in-class, closed-notes, closed-book investigative task tomorrow. Be sure to bring your calculator!
Update: You will be permitted use of your notes (but only your notes, no textbook) on tomorrow’s investigative task.
Today, we start our Mid Year Group Projects by forming groups of 2-3 and starting to think about ideas. We’ll be spending most of the time before winter break working on this projects, and this project will be a major portion of your second marking period grade. Information about projects, including general information about expectations for the project, a description of expectations for the written report, the project proposal form, and a schedule for December can be found here. Note that the first due date is Thursday, November 30th. For now, keep thinking about project ideas!
Your test will be on Friday, December 1st. We’ll spend most of Thursday reviewing any questions you have from the review: 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41 from pages 331-336 in the textbook, which you should complete by then.
Finally, remember that tomorrow we will be doing our Chapter 12 Investigative Task in class.
We didn’t quite finish reviewing the Chubby Dogs experiment, so you can find my answers here.
Next week is going to be an important one for us. Here’s what’s in store:
- On Tuesday, we’ll be completing an Investigative Task for Chapter 12. It will be an in-class task, assigned and due within the class period. Please do not be absent on Tuesday.
- On Friday, we’ll be taking out Unit 3 test, so while the review assignment won’t be due until Thursday, you may want to get started on it now: from pages 331-336, 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, and 41.
- On Monday, we’ll be starting on our midterm projects. More details about the project will be discussed on Monday, but you should get started thinking about ideas you’d like to investigate. Listen to the Freakonomics or Hidden Brain podcasts for some inspiration, or rewatch some episodes of Mythbusters (or check out the archive here). You will be working in groups of 2-3 for this project, no individual projects allowed without very special permission!
Complete the Chapter 10 Investigative Task. As usual, your response should be completed in a Google Document and submitted to me (firstname.lastname@example.org) by the beginning of class tomorrow. Please name your file appropriately. The file name should have the format “LastName.FirstName.Ch10InvTask”. For example, mine would be “Kirk.Benjamin.Ch10InvTask“.
Also, read the first few pages of Chapter 11 (pages 280-285, up to the section on Simple Random Samples). We will start class tomorrow with a reading quiz using the Just Checking questions on page 285.
From page 279, do exercises 31, 33, and 36. Also, be forewarned that there will be an Investigative Task assigned tomorrow and due Thursday. Make sure you have time tomorrow to complete the task!
Complete the Chapter 7 Investigative Task. As before, your response should be completed in a Google Document and submitted to me (email@example.com) by the beginning of class tomorrow. Please name your file appropriately. The file name should have the format “LastName.FirstName.Ch7InvTask”. For example, mine would be “Kirk.Benjamin.Ch7InvTask“.
As I noted in class, Plotly is unfortunately not going to be all that helpful for this particular task, so instead I want you to refer to this page from Macmillan Learning. It has a number of helpful graphing tools that we may continue referring to later, but for now you specifically want the Two Quantitative Variables page. I demoed this in class, but please see this video for another explanation on how this page works.
Finally, don’t forget that you are not permitted to use resources other than your notes and textbook to complete your task (beyond the graphing tools posted above). I strongly encourage you to refer to your textbook specifically for examples of what a complete response looks like.
Finish reading Chapter 7 (pages 189-198)
From pages 200-204, do exercises 18, 22, 23, 24, and 48.
And read over the Chapter 7 Investigative Task. You’ll be able to work on it over the weekend, and it will be due promptly on Monday, October 16th.
Complete the Chapter 4 Investigative Task. As before, your response should be completed in a Google Document and submitted to me (firstname.lastname@example.org) by the beginning of class tomorrow. Please name your file appropriately: the file name should have the format “LastName.FirstName.Ch4InvTask”. For example, mine would be “Kirk.Benjamin.Ch4InvTask“.
I recommend using Plotly to make your graphs. There are some general recommendations and instructions here: Using Plotly.
Read pages 83-90 and 93-95 (skip the section about re-expression), then from pages 100-102, do exercises 20, 26, and 27.
Also, read over the next investigative task, this one about Automotive Safety. We’ll spend some time answering questions about the task expectations tomorrow, then look at an online graphing tool that I recommend you use for this and future projects. As before, your response for this assignment will be due Friday.
Finally, in class we practiced comparing distributions of data using this classwork sheet. We didn’t have the time today do finish discussing it, so if you have the time to complete this tonight, please do. This is a bottom priority, though, and will not be part of tomorrow’s HW check.
Complete the Chapter 2 Investigative Task tonight. Note again that the scoring rubric is included in that file; use that to make sure your response follows the four C’s: Concise, Complete, Correct, and in Context. Your response should be completed in a Google Document and submitted to me (email@example.com) by the beginning of class tomorrow. Make sure that you allow for editing when you share it with me (don’t leave it as view only)
Per the AP Statistics Course Expectations, please name your file appropriately. The file name should have the format “LastName.FirstName.Ch2InvTask”. For example, mine would be “Kirk.Benjamin.Ch2InvTask“.
If you’re confused about any of this, or are having trouble submitting your work, please email me at the above address (or at firstname.lastname@example.org) or leave a comment here.
Finally, don’t forget about the clarifications I made in class:
- The statistics given are numbers of death penalty sentences out of murder convictions. Every single one of the 667 cases described was a murder conviction, of which 115 resulted in a death penalty sentence. Your task is to determine whether the death penalty sentencing rate is associated with race.
- References to the “defendant” indicate the individual convicted of murder. References to “victim” indicate the individual the defendant was convicted of killing.
If you’d like to learn more about Simpson’s Paradox, see my Mathematical Musing post on the topic, or check out this page with some interesting applications allowing you to see its effect more clearly.
Start reading chapter 3, pages 43-51 (stop after the Just Checking section)
From page 41, do exercise 39
From page 73, do exercises 5, 7, 9
Read over the first Investigative Task. You will be working on this in class tomorrow, finishing it for homework tomorrow night. It will be due at the beginning of class on Friday. The grading rubric that will be used to evaluate your response is included in the document. Use this to inform the completeness/thoroughness of your response.
