Plotting Residuals on your Graphing Calc (the fast way)

1. Go to Statplot (2nd, y=)

2. Turn Plot 1 on.

3. Have your data entered into L1 and L2.

5. Select a scatter plot to graph:

x-list: L1

y-list: RESID (you can choose RESID by hitting 2nd STAT and scrolling down to RESID (#8 on my calc).

6. Zoom #9 to see the residual plot.

**Note: I can store my residuals into a list by simply going to an empty list and selecting RESID (2nd STAT) when highlighting the list and pressing enter. Try going to a blank list to do this. It works for me.

AP STATS FINAL PROJECT OVERVIEW/First 2 Assignments

Sample Assignment 2

My Senior Thesis at Swarthmore (helpful for writing a method, abstract, etc.) - All components on your project will be much, much shorter. Note the project's relevance to this recent NYTimes article. (esp. regarding serving size).

Journal Article Example: Maximizing vs. Satisficing (from my two thesis advisors at Swarthmore). - if you are interested in their work, Professor Schwartz has a popular book called "The Paradox of Choice" where he explains his research.

__STUDY FOR THE CHAPTER 11 TEST (Wednesday, March 5th)____I will be collecting HW 10-13__. I have posted AP MC questions and solutions (quite tricky regarding type I and type II errors). You should also reread (particularly definitions of type 1 errors, type 2 errors, and power of a test). There is a summary of the chapter from an AP book as well. I also posted the review game slides from today with MC questions and solutions.

AP STAT BOOK LESSON

AP STAT MULTIPLE CHOICE (only do 1-8, 10, 13, 16, 18, 19, 21, 22, and 24)

Solutions to MC

Finally, do some extra problems from the textbook. Review exercises!

Here's a story to illustrate a few points. Let's say that you are trying to prove that caffeine IMPROVES performance on the SAT. The null hypothesis is that caffeine has no effect on SAT scores. The alternate hypothesis is that caffeine improves your test scores (>). Let's set a significance level at 0.05. That means that there is a 5% chance of rejecting the null hypothesis, if the null hypothesis were in fact true (a type 1 error). We need enough evidence to suggest that caffeine improves test scores and that our results were unlikely to be have caused by chance variation (thats the whole point of setting a significance level).

Now let's say that caffeine really does improve SAT test scores. A type 2 error would be accepting the null hypothesis (saying that caffeine doesn't work), when the alternate hypothesis was actually correct (i.e. caffeine does improve test scores). A type 2 error is failing to reject the null hypothesis when the null was in fact false.

So what's power? Power is the probability of rejecting the null hypothesis if the null hypothesis is in fact false. It is equal to 1 minus Beta (a type 2 error). Think of power like this: it is the probability of convicting a person of a crime who is in fact guilty.

__HW #13: Type I and Type II Errors.__Unit Test on Ch. 11 Wednesday (start studying!!).

Rough Draft of Project proposals are due Thursday (see below - hard copy handed out in class). Final Draft is due Friday.

This is a nice reading to do to review for the Unit Test on Thursday. We will be doing some Multiple Choice on Wednesday to review (I attached some of them below).

Part 1: AP BOOK - lesson

Part 2: AP BOOK -lesson

Multiple Choice Questions on Probability (also free response questions too)

Solutions to MC

__HW #37: Discrete and Continuous Random Variables__Read section 7.1

Complete Exercises 7.11 (b-e), 7.12, 7.13, 7.14 7.16, 7.20 (use Table A)

Quiz on 7.1 on Monday.

No explicit homework tonight but I would suggest spending 25-30 minutes working through the practice problems that we started today. Check your answers on the solutions that I posted below. I also posted a video below (12 minutes) which is of me going over 6.101, 6.106 and 6.108. Below are some Multiple Choice Questions as well. We only know how to do some of them. I will indicate the numbers this evening.

__HW #36: The end of 6.3 (extended problems and more Bayes).__Finish reading 6.3.

6.3 Review Exercises: 6.85, 6.88, 6.90, 6.93

Be sure that you are reading and completing your homework every night to stay current with the material (doing homework all right before a test is no way to learn)!

I also have all the PowerPoints up to date under lessons.

Reminder that we will be reviewing Chapter 6 on Thursday but won't have our test until Thursday before break December 19th). The test will be on both Chapter 6 and Chapter 7.

__HW #35: Probability__Read section 6.3

Complete exercises 6.72, 6.73, 6.74, 6.76, 6.77, 6.82

A reminder to send your project and to bring a hard copy by the end of the day. Thanks!

Change of plan: We will have a test that covers all of Chapter 6

**7 on the Thursday, December 19th! (this is different from what I originally said today). The chapters fit nicely together!**

__and__

__This weekend:__1.) Complete your project #3. Email it to me by Monday and hand in a hard copy in class. Remember, this doesn't need to be long….. just precise in your meaning.

2.) Also, read section 6.2 and be ready for an open notes/open textbook quiz on 6.2. It will be very brief. Complete exercises if you need some practice from the section review.

__HW #34: Simulation (6.1)__Read section 6.1 (this is important to ensure that you understand the concepts.)

Complete the following "quiz" which is just a regular homework. You may print it out, or just complete it on looseleaf paper to be handed in for our next assessment.

HW #34

Optional: If you need more practice with this concept, think about trying exercise 6.13 and 6.19 (these are optional though).

__Chapter 5 Test Tomorrow:__Be sure to have HW #31-33 as well. Use the PowerPoints, Problem Sets and textbook to help you review.

**We will be doing a review tomorrow of Chapter 5 and taking our chapter 5 test on Wednesday.**

__Reminders:__Project 3 is due Monday.

__HW #33: Experimental Design__Complete all the multiple choose problems (note that the solutions and explanations are at the end.) Also complete Free Response Question #1 and #2.

HW #33: Experimental Design

Project #3 (handed out in class)

__HW #32: Experiments__*Read section 5.2*

*Exercises #: 5.35, 5.36, 5.39, 5.40*

*BRING HEADPHONES TO CLASS!!! AND A COMPUTER OR SMART PHONE!*

__IMPORTANT NOTE:__

*For Tuesday's class, please bring headphones, your computer, or smartphone. We will be using them for an experiment!!*

__HW #31: Biases in Samples__**Complete all of the EVEN multiple choice problems handed out today. I have also posted the corresponding "lessons" about these topics from an AP prep book. These are great problems to review for our tests as well. If you are feeling bold, try them all. Or save the odd numbered ones for studying for our test on Chapter 5, which will be after thanksgiving.**

__Part 1:__**Complete the reading that was handed out to you. In your HW journal, write 2 sentences about a key point or two that was an important idea from the article.**

Topic 7 MC

Lesson from Topic 6 and 7

__HW #30: Read section 5.1 (the whole section)__It's just reading tonight... but, please do the reading to stay up to date with the material. It's not a bad idea to make flashcards of the types of samples and biases from this chapter as there are quite a lot of terms that are important to know.

I have your HW journals still. I will be giving out some AP multiple choice questions and free response questions for the weekend.

PLEASE BRING YOUR COMPUTERS TO CLASS TOMORROW (Tuesday)!!!

__USEFUL TEST PREP MATERIALS (CHAPTER 1-4)__One of the best ways to improve on Multiple Choice Questions is to practice multiple choice questions. Below is a really nice set of multiple choice practice problems on topics that we have covered from an AP Prep book. It is very extensive and there are a huge number of problems. They correspond with each of the chapters that we have worked on in class so far. Please use these to help you study. We will be looking at these tomorrow as well. The answers are included at the end of most of the sections. We worked on one two of these multiple choice sets already (Topic 4 and 5 in class).

Multiple Choice Problem Sets:

TOPIC 1: Graphical Displays (stemplots, boxplots, histograms)

Lesson from Topic 1 from Ap Stats Prep Book

TOPIC 2: Summarizing Distributions (histograms, skew, mean, median, z-scores)

Answers to MC Questions for Topic 2

TOPIC 3: Comparing Distributions (comparing graphs)

TOPIC 4: Bivariate Data (scatterplots)

TOPIC 5: Categorical Data

Lesson from Topic 5 from AP Stats Prep Book

__HW #29: Review for the Chapter 1-4 Test (complete the exercises below)__Chapter 4 Review Exercises: Page 316-319: #4.50, 4.52 (or 4.55 or #1.8 in the cumulative review-your choice ), 4.56

Cumulative Review: Page 320-323: #1.3, 1.4, 1.10

**Our CUMULATIVE Test on Chapter 1-4 will be on Wednesday (11/20). The questions will be AP level questions and the format will be similar to our previous tests (half multiple choice and half free response). There will probably be MORE multiple choice questions than our previous tests however (in other words, it will be a bit longer). It will have a slight focus on Chapter 4, but not by much. It will mainly be a mix of problems from Chapter 1-4. The questions will be pulled from practice AP exams on topics that we have covered.**

__REMINDER:__I will be checking HW #26-29 the day of the test (Wednesday).

__Study Tips: Start studying this weekend!!__Reread Chapter Summaries (Chapter 1-4) or chapter if necessary

Look at notes/old tests/quizzes.

Complete review problem sets

Powerpoint slides are also online.

We will be doing a more cumulative review on Tuesday.

-Complete the open notes/textbook quiz for tomorrow.-Read 4.3

__HW #28: Relationships between categorical variables__Read all of section 4.2 (or read the review of this section from an AP Stats review book below). We will have an open notes quiz tomorrow. You will start it with a partner in class and finish on your own that night.

Also complete exercises 4.23, 4.36, 4.39 (this problem is a bit tricky... below is an example of a solution).

Solution to #4.39

A summary of section 4.2 from an AP Stats Book

**HW #27:**Complete Multiple Choice Questions 21-31 for HW from the packet handed out today. The answers are on the last page by the way.

Read section 4.1 of your textbook if you need reinforcement of what we learned today (though it is not mandatory). Additionally, I posted the slides and the page or two about this topic from an AP Prep book below.

NOTES ON LINEAR TRANSFORMATIONS FROM AP PREP BOOK

__HW 26: Free Response Question__Complete the exam prep open response problem #3 (handed out in class - link below). If you have some free time this weekend also take a look at the chapter from Daniel Kahneman's book (Thinking, Fast and Slow) - Regression to the mean.

Open Ended Question (HW 26 - Handed out in class)

Regression to the mean (Kahneman Chapter)

AP MC Questions from Chapter 3 (handed out in class)

We will be covering Chapter 4 very quickly next week. We will be basically skipping 4.1 (or covering it at lightning speed, but I would suggest reading it in the textbook. I will also give you a brief handout of a nice overview of the basic idea here.)

__REMINDER:__**Projects are due on Thursday. Please email me your project and bring a hard copy to class.

**I will give you 15 minutes of class time to complete your course evaluation on Thursday. If you do this at home before Thursday than you will have the beginning of class free on Thursday. Remember that I take this feedback seriously and use it as a way to improve as a teacher and know what is working and what is not! Thanks for your time on this!

P.S. your Chapter 3 test grades are posted on engrade. They were curved by 6 points. What happens to the mean and standard deviation when you curve in this manner?

__REMINDERS:__**-Chapter 3 test tomorrow**

Complete Exercises 2.1, 2.2, 2.3, 2.4, 2.5 (a-c), 2.8

Again, I will not check HW until our next quiz, which will most likely be early next week (so it is up to you when you complete your HW. However, I would highly suggest doing your HW every night!!

We will most likely have a quiz on Tuesday, October 8th.

__NO HOMEWORK Tonight!__Test scores are up on engrade for those who have already taken their test. I can't hand them back tomorrow though as a few people have yet to take the test.

__CHAPTER 1: UNIT TEST TOMORROW__

__GET TO CLASS RIGHT AT 8:10AM Tomorrow (that way you have enough time to finish the test!)__

-10 Multiple Choice Questions

-4 Free Response Questions (some with multiple parts).

We will treat tests in our class like the AP exam. The actual AP exam has 2 parts (a 90 minute Multiple Choice Section and a 90 minute free response section). Both are weighted equally in your grade. There is NO penalty for guessing on multiple choice questions (this is new from several years ago).

Our test will be weighted the same way. 50% of your grade will come from multiple choice questions and the other 50% will come from the 4 free response questions.

I will also collect your HW journal tomorrow to check HW #10-13. Be sure to bring this to class.

Review by rereading the textbook, looking at HW problems, and looking at your notes and slides that I posted online. Feel free to email me with any questions or meet during one of my free periods.

__COMPUTER LAB ACTIVITY__Here is the data that we used in Minitab today. Remember that if you want to get a free copy of minitab on your PC for 30 days just go to www.mintitab.com and download a copy. After that, it costs $29.99 to rent for 6 months (which will cover the year) or $99 to buy for students. This is not required though as it is available on school computers.

SURVEY DATA

Instructions

__TUESDAY, October 1st:__We will be doing some review for the test tomorrow and spending the majority of our time in the computer lab with Minitab (so that you have the tools to do graphs and analyses for your project). If you are interested in getting a free 30 day trial of the program on your home computer simply go to www.mintitab.com. They also have a 6 month license for $29.99 for students (typically the program costs $1400).

We will be using this program all year and it is available in Lubrano, but if you want a copy for home, it might be a good idea to get the free trial for the month and then to think about paying for a copy for yourself for the 6 months after (though this is not required). Note: It unfortunately only works on Windows.

__IMPORTANT NOTE: __Our Chapter 1 Test will now take place on Wednesday, October 2nd!! Remember that I will be checking your HW journal (HW #10-13) on the test day.

We will review and go to the computer lab on Tuesday.

__IMPORTANT NOTE:__

__HW #13: Review for the Test.__

(Page 106-111) #1.60, 1.61, 1.63, 1.66, 1.68, 1.70.

Also, be sure to reread parts of Chapter 1, read the summary and look at old HW problems. The AP questions we did in class are a good way to review some multiple choice questions too (though keep in mind that some of them are a tad bit advanced given what we know so far). I'll try to post these this weekend.

*NOTE: I lied to you today!! Well I just told you something that was false regarding the 1.5 IQR rule.*

A data point is an outlier if the point is 1.5 x IQR greater than the __3rd quartile__ or less than the __1st quartile__. I mistakenly told you it was above or below the median. In other words the point needs to be even more extreme of a value. Sorry for the mistake!!

HW #3

__HW #3: Chapter P: Pg. 11 Exercises P.1-P.5.__

__HW #2: Finish the Video and Design an Experiment.__

Finish the video (What is Statistics?) that you started for HW #1 (i.e. you should have watched the full 28 minutes).

http://www.learner.org/vod/vod_window.html?pid=139

Come up with an experiment of your choosing to test a claim of your choice (feel free to be outrageous if you like).

For example: I might want to test whether students who eat an apple 15 minutes before an AP Statistics test tend to do better on the test.

1.) What claim are you testing?

2.) What is your hypothesis for the result of the study?

3.) How would you conduct the experiment (be specific)?

4.) How would you draw conclusions from your findings (i.e. how would you know if your result was valid)?

Optional: Take a look at the news over the weekend. Do you see any studies/examples that might involve statistical insight? Share them with the class on Monday!

As an aside, I tabulated the results from the Coke/Pepsi and Fiji/Tap water studies. Our results are statistically significant. I'll explain what that means on Monday. For now here are the basic findings. There was a 0.6% chance that the results we found were due to chance for the Coke/Pepsi study (this is called the p-value in statistics). In other words, we can be 99.4% sure that the results we found were not merely due to chance. This suggests that on average, my AP stats class can in fact tell the difference between Coke and Pepsi.

For the tap water/Fiji study the results are even more pronounced. There was only a 0.02% chance that the results we saw were due to chance. In other words, we can be 99.98% confident that the results we saw were not due to chance. This means that we can pretty conclusively say that our class could tell the difference between tap water and Fiji bottled water.

__HW #2: Finish the Video and Design an Experiment.__

__Homework #1: What is Statistics Video __

__Due Friday, September 6th, 2013__

Congratulations! You have made it to my webpage and have found your first assignment. Your homework will always be assigned on this webpage. Please get a journal or spiral notebook with graph paper, which will be your homework notebook for the year (available in the bookstore).

Please watch the first 13 minutes of the video entitled "What is Statistics?" in the link below. The video is 28 minutes long and you will watch the rest of the video over the weekend, so feel free to watch the whole video if you like for Friday, but it is not required. You probably will need to scroll down to the first video that says "What is Statistics?" and click the link that says VoD next to it (I have had to click on it two times for it to work for some reason). Make sure you are watching the 28 minute video (not the 5 minute video).

1.) After watching the video, what are some practical reasons that we study statistics?

2.) What is a question that you have about statistics after watching the video?
