Read Chapter 4 tonight! Remember, notes are optional, but if you do take them you can use them on our reading quiz. Don't worry, the reading quiz is just to check you read--not see if you can do all of the math just from reading!
And we have a quiz Thursday!
And I know I said I'd put the answer to 21 on the blog--but I forgot it's an odd!--so check the back of your book!

Labor Day HW
Yo yo yo! For the three day weekend I need you to complete all of the problems on the handout I provided in class Friday--EXCEPT NUMBER 20!
I know this is tough...try your best and we'll talk about it all Tuesday. However, don't give me a little "i didn't get it" and expect credit. This course is all about THINKING. So try your best, and you'll be aight.
And yes, I'm checking. Here's some help...
Number 21 asks you to investigate whether admissions decisions are independent of race/ethnicity. Well, if they are in fact indepdendent, we should see the same proportions of accepted students as in our total applicants. Think about it--if your ethnicity doesn't matter and 40% of our applicants are white, then we'd expect that same 40% to show in our accepted students.
So, here's how we start. First, we need to find the overall percentages of each group. What percent of everyone was Black/Hispanic? What percent of everyone was Asian? What percent of everyone was White? Calculate these three values.
Next, we want to look at only the accepted students. What percent of the accepted students where Black/Hispanic? What percent of accepted students where Asian? What percent of accepted students were white?
To conclude, we compare these values. If the overall proportions match up with the "accepted" proportions, then admissions decisions and race/ethnicity were independent.
Good luck!

Tuesday Aug 31 HW
First day of hw!
Simply read through each of the stat raps and circle/underline/highlight as many statistics references as you can. Please don't guess--identify those references you're confident are related to stats. Then tally these and record the total; we'll use this data for our classroom explorations.

First Day Homework!
It's here! A new year, new classes, new challenges. And most importantly, a new chance for us all to start fresh and set the sky as our limit. In other words, we're going to dominate AP Stats all year and prove it on the AP Exam.
I'm very much looking forward to seeing you all for our first day! I'll be getting everything squared away, making photocopies, and all that other good stuff today (Monday); when you arrive on Tuesday we'll hop right into some statistical thinking.
Just so you know, here's the tentative plan:
Tuesday: read our first article, discuss, start thinking statistically
Wednesday: Chapter 2: What is Statistics?
Thursday: Chapter 2 Wrap-Up/Start Chapter 3
Friday: Chapter 2 QQ, Finish Chapter 3
Tuesday: Chapter 3 Wrap Up (study for your quiz!)
Of course that's just a plan, and as you'll learn about me, my plans are always tentative :)
First extra credit opportunity--if you come to school on the first day with this schedule written, as well as two other things you liked about the blog (so you have to explore the blog), you'll get 3 points on the first quiz! (And this is all or nothing--no partial EC)
See you all in a couple days! I'm pumped!

New Stat Kids!
Yo! This is the first official post devoted to all my new stat kids. I'm currently sitting in a classrom at Eastern CT State U. getting my statistics on. Literally as we speak I'm looking through each and every powerpoint and worksheet, trying to find any and every place I can improve, as well as getting some great ideas from stat teachers across the state.
As for your summer responsibilities, relax, recoup, and get ready for a tough but rewarding year. I'm already starting to feel excited for a new start and a new stat group; get your brains ready for a bunch of hard work. I think you'll really find it to be a rewarding class, not only in improving as a student, but simply in appreciating the craft of statistics.
Over the summer take some time to familiarize yourself with this blog. I plan on making this site a staple in our classroom throughout the year. Look at all of the resources you have at your disposal; take some time to look through some of the early chapter powerpoints and what we'll be starting with; and of course, take some time to really listen to the stat raps for a preview.
I hope all of you have had an enjoyable summer. At some point in August I'll be posting an extra credit opportunity--easy points, you just need to keep checking the blog to find out!
YOU WILL HAVE HOMEWORK ON THE FIRST DAY! Until then, enjoy all your days and nights. I will see you all soon.
