AP Statistics Assignment for 11/1

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.

Mathematical Musing: What is r (Part 2)?

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!

Greetings IHS Parents/Caregivers!

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!

AP Statistics Assignment for 10/16

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.

A quick note about grades in SchoolTool

To all Students and Parents/Caregivers

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.

AP Statistics Assignment for 10/13

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.
