If you want to look again at my response to the Chubby Dogs experiment, you can find it here. Remember that we will have an in-class investigative task tomorrow, where I will ask you to design an experiment for another situation. This will be a closed-notes, closed-book task.
We started our discussion of the mid-year projects today. All of the details for the projects can be found here.
You’ll have some time on Thursday to finalize your idea and start work on your proposal, but you will likely need to spend some time out of class to finish it, as the proposal is due at the start of class on Friday the 30th.
On the 30th, we’ll spend some time reviewing Unit 3 for our test on Monday, December 3rd. By Friday, please complete the review assignment found on pages 331-336: exercises 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41
Finish up Chapter 12 by reading pages 319-325 and doing exercises 32, 33, 39 from pages 327-329. Also please finish the Chubby Dogs Experiment example we started in class.
Upcoming Items of Note
- Tomorrow, we’ll introduce the mid-year project. You’ll be forming project groups and brainstorming ideas initially, and will finalize your idea and submit a project proposal by Friday. If you want to preview the details of the project, you can find information here.
- Wednesday, we’ll have an in-class Investigative Task for Chapter 12. This will be a closed-notes, closed-book task!
- Next Monday will be our test on Unit 3. After you submit your project proposals, we’ll spend the rest of Friday reviewing. I would suggest you get started on the review assignment (will not be checked for homework, so don’t stress!): pages 331-336, exercises 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41
Read pages 313-319 (stop when you get to “confounding”), then work on exercises 6c, 14, 15, 17, 30 from pages 326-328.
After break, we’ll be starting work on our midterm projects. More details about the project will be discussed next week, 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!
From the text, read pages 305-313, up to the section on Experiments and Samples.
From the exercises on pages 325-326, do 1, 2, 3, 9, 13
Happy snow day, all! I hope you are able to stay warm, dry, and safe today. It was a mess out there this morning, and it still is in many places, so if you can avoid going out you probably should!
There will be no make up assignments over the weekend for any of my classes, with the exception of AP Statistics. For you, I would like you to watch a pair of videos that will give you a solid introduction to our next chapter about observational studies and experiments. They are
- The Question of Causation – A historical story describing how researchers untangled the relationship between smoking and lung cancer
- Designing Experiments – A discussion of the difference between observational studies and experiments, with examples about marine life on the remote Line Islands and a medical study about osteoarthritis treatments.
Have a good weekend!
From pages 302-303, do exercises 26, 27, 33, 35, 36
From pages 302-303, complete exercises 18, 23, 25, 30, 32

Over the weekend, continue reading chapter 11: pages 285-291, up to “The Valid Survey,” then do exercises 4, 7, 8, 12 from pages 300-301.
Finish the Chapter 10 Investigative Task assignment that you started in class. This will be due at the start of class tomorrow, and as usual, your response should be completed in a Google Document and submitted to me (firstname.lastname@example.org). Please name your file appropriately. The file name should have the format “LastName.FirstName.Ch10InvTask”. For example, mine would be “Kirk.Benjamin.Ch10InvTask”.
Please also read the first part of Chapter 11, pages 280-285 (up to the section on “Simple Random Samples”). There will be a reading quiz tomorrow using the “Just Checking” questions in that section.
From page 279, do exercises 37 and 38
If you’re looking for my fully worked out solutions to yesterday’s simulation sheets, you can find them here (4-H eggs) and here (Duck Hunt)
From pages 278-279, do exercises 28, 29, 33, 36
You will be given an Investigative Task in class tomorrow to review and start, then finish for tomorrow night’s homework.
Record your results for simulations in class here.
For tonight, from pages 277-278, do exercises 7, 12, 14, 20
Read pages 267-276 (all of chapter 10) from your textbook, then do exercises 11, 13, 17 from page 277. These ask you to design and run a simulation. Do at least 20 trials!
For tomorrow, you should complete the multiple choice questions (1-15) from the Unit 2 Practice Exam – pages 264-266.
In addition to that, you were given a novel task in class today. I am asking you, based on the draw of a card, to either actually flip a coin 200 times and record the results or to make up the results of 200 coin flips and enter them on this sheet. If you weren’t in class today (Thursday) to get your assignment, flip a coin one time first to see which version you will actually be doing: If it is heads, flip the coin 200 more times; if it is tails, make them up.
If you picked up an extra credit sheet in class after the test, that is due tomorrow (do not ask me for extra copies of this sheet).
For Friday, you should complete the multiple choice questions from the Unit 2 Practice Exam – pages 264-266.
Your Unit 2 test is tomorrow, so spend some time reviewing/studying for it. Consult the Unit 2 Review Materials for answers to yesterday’s textbook assignment and a handful of additional practice problems. Feel free to work on more problems out of the review section of the text. I can share my answers.
One more reminder: your Unit 2 test will be on Wednesday, October 31. It will be cumulative for the entire unit, including chapters 6 and 7 that have already been tested, along with the content from chapter 8 (outliers, primarily) and chapter 9 (re-expression)
We’ll have another review packet in class tomorrow. For tonight, please work on the textbook review assignment: Read the summary information on pages 255, then from pages 257-261, do 10, 11, 16, 19, 20, 22, 23, 30.
Finish reading chapter 9 (pages 242-246), then work on exercises 18, 19, 30 from pages 251-254.
We will have our Unit 2 test on Wednesday, October 31.
No reading assignment tonight, but please work on exercises 6, 16, and 17 from pages 248-250.
The date of our unit test has been shifted. It is now scheduled for Wednesday, October 31st.
