Student Conference/Field Day

Short note: If you are here during 2nd period and wish to review and vote on choices for next year’s school musical and play, click here.

On Monday, June 17th we will be having our first annual Student Conference Day to complement the field day that we have traditionally had on the last day of classes. This is an opportunity for you to create your own schedule of interesting activities through the first part of the day, followed by the end-of-year celebration/relaxation of field day.

Your specific expectations depend on what class you’re in, so check the sections below. The general schedule is as follows:

  • 8:55- 9:20 (Period 1): Review of Day, ICSD Goals and Priorities Survey
  • 9:25-10:25 Session A
  • 10:30-11:30 Session B OR 9th Grade Lunch
  • 11:35-12:35 Session C or 10th Grade Lunch
  • 12:40-1:40 Session D or 11th and 12th Grade Lunch
  • 1:45 – Return to Period 1 – Leave belongings and await directions for Field Day

For AP Statistics Students

You should review the session offerings at the online Google site here or on the summary listing here and sign up for sessions on the Google site. If you want to go to a session instead of going to lunch, that is okay. Make sure you email yourself what sessions you are going to so you don’t forget, and note that the off-campus sessions (Mr. Heurich’s hike, Ms. Snowman’s nature walk, and Mr. Breigle’s Incodema visit) require an additional permission form.

For my 1st period Statistics students, since I will not be in first period to check in with you on Monday, you have been instructed to go to York Auditorium for your start-of-day instructions. You can plan to come to G102 in the Session D/Field Day transition, however. I’ll be back in the room by then.

For my 6th period Statistics seniors, if you do not have a first period class, you should go to H-courtyard.

For Intermediate Algebra Students

Unless you are designated as having extended time on exams, you will be done with your test by noon and so you should sign up for a workshop during Session D. I’d also recommend you look at Session C options in case you finish the exam early.

You will report directly to the gym by 8:45 so that we start our exam by 9. The concessions stand will be open to drop off your phone, backpack, etc., or you can leave these items in your locker. You will spend a minimum of 1.5 hours in the gym. Once you have been released, go to the cafeteria and get lunch. After you eat lunch, head to Session C or Session D.

After Session D, head to your 1st period class to drop off your bags for Field Day. If you do not have a 1st period class, head to H-courtyard.




End of Year Information/Final Post!


There is a lot of information to cover in this post, so please read on!

Thank you for your time and attention this year. I hope you’ve had a good year, and I hope that you’ve found your time in my class to be valuable. We’ve had a long year, though at the same time it really seemed to fly by!

As you know Monday will be the first annual Student Conference/Field Day. There is a lot to know about this day, but what you specifically need to know depends on what else is going on for you on Monday. This information is addressed in a separate post.

For all students

Please complete the course evaluation form found here. These evaluations are crucial for me to improve the course content and structure to better serve my students, as well as to improve myself as a teacher. I read every response carefully. I am not collecting names or email addresses (unless you *want* to include your name!) so please be honest!

For AP Statistics students

  • Submit your written report and your presentation to me (and Ms. Seifert if you are in 1st period) using the filenames “LastName.LastName.LastName.Final Project Report” and “.Final Project Presentation”
  • Make sure that your data sheets are linked in the appendix of your written report and the sharing settings are properly set so that I can view them!
  • By June 21st, please complete the peer evaluation form here. Submit a response for each member of your group, including yourself! Failure to complete this evaluation will impact your final project grade!

For Intermediate Algebra students

Your final exam will be on Monday, June 17 at 9:00 in the big gym. I’ve uploaded some final thoughts and hints about the exam here. Please take some time to look it over! Report to the big gym on Monday by 8:45 so that we can start the exam promptly at 9:00!

Review Notes and Assignments

Cumulative IXL Review Modules

AP Statistics Final Project Information

Per the Post-AP Schedule, the rest of our time in class will be spent working on final projects. All the information about requirements and expectations can be found in the Google Drive folder here.

Next Due Date: Your completed written report is due on Friday, June 14. You’ll have some time in class to put on some finishing touches, but it should be more or less done by Friday.

AP Statistics ANOVA Assignment for 5/22 (due 5/28)

We finished the lesson on ANalysis Of VAriance (ANOVA) today, and you have a short assignment to complete based on it.  Please note that you really don’t need to do most calculations by hand; you can do them on the calculator.  The assignment will count towards your marking period grade.

  • ANOVA Powerpoint – the slide show I used in class (the link to the site with the practice tables is here)
  • ANOVA Homework – Due on Tuesday, 5/28
  • F-table – for running the Scheffe Test.  Note that if you need a df that is not on the table explicitly, you should use the next highest value (e.g., there is no 35, so use 30).


AP Statistics Post-Exam Details

Our current plan for the last four weeks of classes can be found here: Post-exam/Final Project Schedule. Most of this time will be spent working on final projects, but we have some other tasks schedule as well, including a discussion of strategies for getting college credit for this course and learning about one last type of statistical inference!

Also, as posted before, you can review the questions from this year’s AP Statistics exam here and my responses here. Disclaimer: this is my own work, based on my own understanding of the questions. I do not guarantee that all responses would be awarded full credit (though I usually do fairly well!). Moreover, I tend to be very thorough with my responses, more than the AP rubrics generally require (especially with the hypothesis test question). Do not be nervous if you did not give quite as much detail as me.


AP Statistics Free Response Questions Posted!

You can review the questions from this year’s AP Statistics exam here. My responses are here. Disclaimer: this is my own work, based on my own understanding of the questions. I do not guarantee that all responses would be awarded full credit (though I usually do fairly well!). Moreover, I tend to be very thorough with my responses, more than the AP rubrics generally require (especially with the hypothesis test question). Do not be nervous if you did not give quite as much detail as me.

AP Statistics Exam Final Thoughts

Your AP Statistics Test is Thursday afternoon. Be outside York Lecture Hall by 11:50 with your calculator and pencils (non-mechanical, remember!). Do not bring your backpack, bag, or your cell phone (or any other “smart” device like watches); find somewhere to put them. You may bring a snack or water, but it must be in clear packaging and you may not have it at your desk with you. Do not expect to leave until at least 4:00!

See this post from before with the archive of review materials.

Things you should be sure to remember (these are my thoughts, see pages 608-610 of your review book for some further points):

  • The formulas for the mean/standard deviation of a sampling distribution of means and a sampling distribution of proportions are on your formula sheet. Whenever you’re being asked to calculate a mean or a standard deviation, check to see if it’s one of these.
    • Related: Pay attention to which standard deviation you are being asked to calculate. The standard deviation of a sample is not the same thing as the standard deviation of a sampling distribution.
  • Probability questions will come in three categories
    • Direct calculation based on a finite sample space (like rolling dice). Write out all the possible outcomes and count which ones are the ones you want. This also includes two-way tables. Don’t try to use fancy formulas for those; just count!
    • Number of successes questions. For example: “how many model E cars would you expect to see in a 2000 car sample?” or “what’s the probability that at least one out of the four drivers is speeding?” These are applications of the binomial probability model and should be calculated appropriately using the formulas on your sheet.
    • Number of trials questions. For example: “how many chips would you expect to need to check before finding a defective one?” or “what’s the probability that the 5th donor is the first with Type-B blood?” These are applications of the geometric probability model. The formulas are not on your sheet, and so you should memorize them: q^(K-1)*p for a general probability and 1/p for the expected value.
  • Know how to combine the standard deviations of two or more random variables. Remember: variances always add.
  • Know how to read the regression output of a linear association. What do “constant,” “estimate/coefficient,” “prob” all mean? Refer to pages 111-112 in your review book or page 729 in your textbook.
  • Know the difference between stratified and cluster sampling and how to identify/use them. Also remember that for a simple random sample every possible sample has the same chance of being chosen.
  • Know the important conditions for each of the inference procedures:
    • Everything: Random Condition
    • Any z-test: Success/failure condition
    • Any t-test: Nearly Normal/Large Enough condition
    • Any chi-square test: Expected cell frequency condition
    • Any 2-sample/2-proportion test: groups are independent from each other.
    • Also: know when to use a 2-sample t-test vs. a matched pairs t-test
  • Be mindful of notation. Don’t use x-bar when you should be using µ. Don’t use p when you should use p-hat.
    • Related: No Naked Numbers! Every number included in any response should have a label somewhere (mean, standard deviation, p-value, etc.)
  • Context, context, context. Always frame your answers in the context of the situation. Don’t say, “I am 95% confident that the true proportion of success is between 22% and 37%.” Say instead: “I am 95% confident that the explosive sensor will accurately detect hidden explosives 22% to 37% of the time.”
  • Be complete with your responses. When choosing between two possibilities in a free response question, explain why one possibility is wrong and why the other one is correct. When asked to compare two distributions, make explicit comparative statements, e.g, “Group 1 is centered at around 12, which is greater than Group 2, which is centered around 7”
  • At the same time, don’t give more information than is requested. If the question asks you to describe the shape of a distribution of data from a histogram, don’t discuss center and spread. If the question asks you to explain your randomization procedure for an experiment, you don’t need to explain what the response variable is, how you’re going to measure it, and what a statistically significant outcome would look like. If the question asks you to merely calculate a confidence interval, you don’t have to interpret it.

AP Statistics Pre-exam breakfast

Ms. Seifert and I would like to invite you to a pre-exam breakfast and review session in her room, H213, on Thursday. We’ll start things up around 8:40 for those of you who don’t have 1st period free, and we’ll spend 1st period hanging out and answering any lingering, last-minute questions you may have.

We plan to get bagels, but if you have dietary restrictions (gluten free, vegan, etc.) please indicate them on this form by the end of the day!

AP Statistics Assignment for Week of 5/13

Your AP exam is on Thursday, in the afternoon. Between now and then, what we do for review is largely up to you. I’ll have some ideas here and there, but I’ll expect you to ask questions and guide what we do for these last few days.

Tonight, you should take a look at the AP Exam tips on pages 608-610. We’ll do some more review with AP multiple choice questions in class tomorrow, but after that it’s up to you!

AP Statistics Assignment for 5/8 & 5/9

By Friday, complete the 2014 released Free Response Questions. On Friday, you’ll get into grading groups and score your peers’ responses according to the scoring rubric. Note that this is a different exam from what appears on your review calendar.

This grade will not be counted towards your marking period average. Please do not review the solutions to these problems. Let this be another opportunity to practice the free response section of the exam. Spend no more than 1.5 hours, and use no resources other than your calculator and formula sheet.

Write all of your answers on blank sheets of paper. More than one solution per page is fine; we’ll staple them together in class. But please make it neat! Your peers will be reviewing your work!

AP Statistics Assignment for 5/7

We reviewed the binomial and geometric probability models today, along with sampling distribution models for proportions and for means. Tonight, please do the following

In addition, I’d recommend you look at section 10 from your review book.

Review my answers here before class tomorrow so we can address any lingering questions you may have more efficiently.

AP Statistics Assignment for 5/6

We did some review of probability today, in particular parts of chapters 14 and 15 of your textbook. Your homework tonight is:

In addition, I’d also recommend you look at Question 3 from the 2008 Free Response, as well as Section 8 of your review book.

Review my answers here before class tomorrow so we can address any lingering questions you may have more efficiently.

AP Statistics Assignment for 5/1

We will have an in-class quiz assignment tomorrow, where I’ll put you in groups and give you an investigative task from a past AP exam to work on. You’ll have the whole period to work on it, but you won’t be allowed to use your notes or text: only your own effort (and the formula sheet).

In preparation, take a look at the Investigative Task section of your review book (Topic 14), then work on questions 1, 3, 6 from problems starting on page 403.

AP Statistics Assignment for 4/30

We reviewed the Linear Regression t-Test, our test for association in quantitative data. Your homework is:

Please review my answers here before class tomorrow so we can more efficiently resolve any lingering questions you may still have, and spend most of the period tomorrow talking about the multiple choice section of the practice AP.

AP Statistics Assignment for 4/29

As we start the next phase of our review for the actual AP exam on May 16, we will be starting with the top two review requests from the survey I ran over the weekend: Unit 7 (Chi-squared and linear regression tests), and Unit 4 (Probability). This review will feature mostly in-class examples and discussion, followed by select AP free response questions as homework. The rough schedule for these next three weeks can be found here.

Today, we reviewed Chi-Square tests. Your homework is:

Please review my answers here before class tomorrow so we can more efficiently resolve any lingering questions you may still have.
