Homework: Wednesday (Collins!)
Here's your assignment for the night...you don't really need any book or resources to get it done, just your brain and something to write with! No excuses!
Task:
1.Outline the process for finding percentages/percentiles using the Normal model.
2.Outline the process for finding a cutoff value, if given “highest 20%,” or “middle 49,” etc.
FCA’s: (each @ 5 points)
1. Student correctly outlines both processes (correct statistical steps).
2. Student correctly/appropriately uses statistical vocabulary
3. Student provides mathematical example for each of the 2 processes above.
Extra Credit for Quiz:
Outline the process for creating a boxplot (like above).

Back to the grind...
Can you believe that progress report grades are already closing this Friday? Craziness.
Homework for tonight: complete the worksheet regarding the Normal model I handed out in. You can skip "part d" on the bottom. And this is not worth 28 points as stated at the top--this is our first practice, so it'll count as any other homework assignment. (Yes, I'm checking.)
I apologize for the lack of real data on this assighnment...it's not usually my style, but this is an actual assignment from a college course so I thought it'd be interesting.

It's the weekend!
Can you believe that this upcoming week is the last week of September? Wow. It's flying by already...before you know it, we'll be on winter break.
Anyway, that's enough dreaming about vacations. For now, you have 9 problems to do for homework.
Page 124: 16-20, 24, 25
Page 133: 15, 17
Do it up! You can expect some review questions on each homework this week as we move toward our Unit 1 Exam.
And now you all have this sweet Barron's review guide to help enhance understanding; if you come in on Monday with "I didn't get it," that's still a 0 on your homework. Of course there's nothing wrong with getting homework incorrect--this is practice--but not even trying something, showing some thinking, is totally unacceptable. Step your game up.

How was the quiz today? (It's not over yet...)
How was it? Today was our first "big deal" quiz I'd say. The chapter 3 quiz we had was pretty intense too, but today's quiz was challenging and worth more points...
But it's not over yet...
Your homework tonight is to complete the 18 multiple choice questions handed out in class...You will be graded out of 10 points for the quiz grade.
ANY EXTRA POINTS YOU EARN WILL GO TOWARD YOUR MC TEST GRADE. So, for example, let's say you got an 15/10 on tonight's multiple choice, but had a 20/30 on the test...well thanks to your hard work, those extra 5 points turn your test into a 25/30. So as you can see, tonight's work is incredibly important. Try to get a 100 and add 8 points to your grade! Work hard!
And if you have the opportunity, work together!

Quiz Tomorrow!
Study! If you want some problems to look at, here are some I picked out from chapter 5 that resemble what's on our quiz. These start on page 91:
3,5, 15, 17, 19, 21, 23, 24(a-d), 29, 31, 37
I know you've done some of these on your homework assignments; these are just the best questions to look at. Here's the format for your quiz:
You have a short answer section that requires you to create a histogram, find mean and standard deviation, describe a distribution, and identify if the mean/st. dev. are appropriate. You're also asked how summary statistics might change if we add a new data value (like #7 on page 92). The other part of this section asks you to read/interpret 4 boxplots and determine how mean is affected by shape.
Then, you'll have an AP question that asks you to create a boxplot and answer a few questions, comparing variability and describing the distributions.
Finally, you'll have 12 multiple questions as a take home portion--but still part of your grade.
3,5, 15, 17, 19, 21, 23, 24(a-d), 29, 31, 37

Weekend!
It's pretty much the perfect temperature outside right now (well, we know I like it cold judging from the class); grab your multiple choice, call up some friends from class, and go sit outside and bust out that test. Multiple heads are better than one; collaborate, work together, and get an A!
So you have the take home 15 questions for a 30 point test grade due Monday. NO EXCEPTIONS! If you forget it or don't have it, you'll be starting your test category (the biggest proportion of your grade) with a 0--no bueno.
On Monday we'll keep practicing with boxplots and have a quiz Tuesday.
Other than that, just enjoy the next two days! Go Giants!
*Just for the record, if you have an urgent/homework question, email me at fred.carofano@gmail.com, I'll see it faster than a blog comment.

Monday....first five day week :(
Homework tonight----finish the 13 MC AP problems! Remember that I'm going to collect and grade this, so make sure you finish! No exceptions! This is 26 points in your Projects/AP Problems category--first grade for this, so do well! Read carefully!
For those interested, here's my plan for the week. On Tuesday we'll start our chapter 5 notes after we talk about the MC from tonight; Wednesday we'll finish these notes. On Thursday, you'll work through your two AP problems in groups, along with a boxplot/histogram activity. Then, Friday, you'll take a quick quiz based on your matching, and then....something else.
Here's my homework plan for the next few days:
Tuesday: Read Chapter 5 (and I already photocopied the reading quiz...)
Wednesday: 5, 9 (can use calc), 11, 13, 17, 21, 23, 27, 29
Thursday: 7, 31b, 33, 35, 39, 47

Thursday, Friday, Monday HW
I'm on top of my game today...early post...
Here's my plan for your homework for the next few days...
Thursday (page 64): 9, 11, 19, 21 (make a histogram), 29, 31
Friday (page 64): 3, 5, 22, 23, 25, 34, 37
Whenever a problem asks you to "Describe the distribution," you need to talk about "SOCS." That is, "Shape, Outliers, Center, and Spread." Tell me the overall shape of the curve (you may need to look in your book for examples of skewed, symmetric, etc.), whether there appears to be unusual values, give me an approximation of the center of the data (just by looking), and talk about how spread out it is (from "10 to 1,000" for example).
On Monday (in class) you'll work in small groups on some AP-style multiple choice questions regarding quantitative graphs and then Tuesday we'll move into chapter 5.
Your homework Monday night will be to reach chapter 5 (if you want to get ahead). Yes, reading quiz….probably a good idea to start reading now...
Now let's see how class goes today and if this plan actually sticks!

Quiz Tomorrow!
For homework tonight finish (a) and (b) on the 2007 Form B AP Problem (stemplot question).
And don't forget to study! Quiz tomorrow on Chapter 3--independence, finding percentages from contingency tables, and some categorical graphs.

Tuesday 9/7 HW!
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!
