Mark the Coin Toss HW according to the color card you were given in class. Red card holders should use an actual coin (or other random phenomenon) to record the results of 200 flips and black card holders should make up the results of their 200 flips.

Also, work on the multiple choice questions for the second practice exam on pages 264-266 (questions 1-15). We will discuss this on Thursday.

Study for your Unit 2 Test tomorrow! Remember, this will cover **all** of Unit 2, including the material already covered by the previous test. You can find the full review packet here.

In Part 1 of this question, we explored how the correlation coefficient is calculated, and how that calculation relies heavily on the **covariance** between two quantitative variables. We left off with a few questions: why is *r* bound between -1 and 1, and why does a value of *r* near 0 indicate a weak association (and near an extreme indicate a strong one)? In this post, we will answer these questions!

Finish reading chapter 9, pages 242-246, and do exercises 18, 19, and 30 from pages 251-254.

We will have our second Unit test on **Tuesday, October 31st** (sorry). In preparation for this, I recommend you work on the following review assignment: from pages 257-261, exercises 10, 11, 16, 19, 20, 22, 23, 30 (and read page 255 for good summary of the unit).

From pages 248-250, do exercises 6, 16, and 17.

The answers to today’s exercises can be found here.

Read pages 232-242 (stop at “Plan B”), then from the exercises on pages 247-250, do 3, 5, 11, 15

From pages 228-230, do exercises 31, 33, and 37.

You will want to refer to this Desmos application for today’s exercise.

For homework, read pages 214-222 and do exercises 17, 19, 22, 25 from pages 225-227. There will be a reading quiz on Monday about the Just Checking section!

Hello and welcome to my website! As I mentioned during the open house, I use this site to communicate with students, parents, and whomever else might be interested outside of class. On this site, you can find assignments, announcements, links to instructional videos and online review, copies of handouts I distribute in class, and the occasional mathematical musing.

Please take some time to check out this website. If you’re looking for course information, you can find it under “IHS Student Quicklinks” in the column to the right. If you’re wondering about how to obtain some extra help for your student, I recommend checking the “Class Information and Getting Help” link at the top. For more general information about what you can find on this site, check out the welcome post from the beginning of the year. Thanks for stopping by!

Read pages 209-214, up to the section on Outliers

From pages 222-225, do exercises 1, 3, 5, 15

No homework tonight apart from the extra credit sheet you got after your test. We will start chapter 8 tomorrow.

Your test on chapters 6 and 7 is tomorrow. You got another review sheet in class today, and you can find both review sheets and the answers to both here: Linear Regression Review Sheets.

We will have a test on Chapters 6 and 7 on **Wednesday, October 18th**. Today and tomorrow, we will spend some time reviewing these two chapters. Everything from these chapters is fair game, except the section on re-expressing data from Chapter 6; we’ll be revisiting that in detail in Chapter 9.

For tonight, your homework is to complete the first Linear Regression Review Sheet. We’ll discuss questions tomorrow.

Please be advised that the grade you get for my class on your progress report won’t necessarily be the same grade you see calculated by SchoolTool. This is because the marking period grade that can be found in the SchoolTool portal is **not accurate**. I use letter grades for a lot of assignments/assessments, and the built-in numerical equivalencies on SchoolTool do not match the ones that I use. **I use the SchoolTool gradebook for reporting purposes only.** Not for grades. I calculate marking period grades separately and have entered them into your progress report.

Complete the Chapter 7 Investigative Task. As before, your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us) 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**.
