Weekend HW

I'm soooooooo pumped about chapter 6!

Here's the weekend homework: first off, please complete the worksheet provided in class (all of it). This means the rest of number 2, and don't forget to go back to #1. For 2, letter i, you need to think--draw a picture to help yourself out! If you need more, check out your textbook.

Second, please find the average SAT score for 3 colleges you're interested in applying to. If you're younger and haven't considered this yet, start now. If you don't plan to go to college you still need to find average scores for 3 schools.

We'll use this as the basis as some of our work next week, so it's important! This research will count as a homework assignment!

Extra Credit:
Today we looked at the populations of the U.S. and China, and then found the number of geniuses in each country. Here's a challenge: find the IQ score that would cut off a percentage of the Chinese population greater than the entire U.S. pop.

Let me try to clarify: today we anticipated that China had about 5 milllion geniuses, based on the .38% of people above an IQ of 40. Of course if we want this number (5 million to increase), we need the percentage to increase--so find me the IQ score that cuts off a high enough percent of the Chinese population that it's greater than the entire U.S. pop.

(Sorry, that's really hard to try to write up).

I'm back! Yay!

It felt good to be back in Stats world. I think I actually missed you all quite a bit.

Tonight, please complete page 124: 15 - 23 (odd).

Tomorrow we'll go through any questions you may have, and keep pushing forward with this z-score stuff.

HW Tonight/Sub Tomorrow

Back to the grind...

Tonight, please complete page 123, 1-11 (odd). Of course I won't be here to check this tomorrow, but I will check Wednesday. It's up to you if you do it tonight or hold off--but you will have some multiple choice to do tomorow night as well.

Tomorrow, please use the 2000 AP problem data to do the following:

1. Draw 2 comparative histograms--so use the same scale on 2 separate axes--for flexibility ratings of young-adult and middle-aged men.

2. Compare the flexibility ratings of young adult and middle aged men.

Once you've graphed this and written your conclusions (talk about SOCS, and don't forget the context--who's more flexible?), you should start the 13 MC questions.

Hope you all have a good day! I'll miss you and chapter 6! Back to work on Wednesday!

Weekend HW

Hope you're all feeling confident after today's quiz! Your homework this weekend is to read chapter 6, and be prepared for a reading quiz on Monday. As always, you can take notes if you like, and any notes can be used on the quiz.

For those of you who prefer to do "math problems," I think you'll like this chapter. I know I'm excited for it! And then, before you know it, we'll be wrapping up our first unit and moving on to bivariate data! Woohoo!

If you're worried about today's quiz here's an opportunity for some extra credit--4 points--

Find a current news story/article that is based on quantitative data and bring it to class. If you bring a data set, please do not bring one with a sample size above 50. Ideally it should address the mean and standard deviation in the study.

Wednesday HW

Please complete the following problems:

Page 90: 10, 14, 34, 35, 42

Remember, we have our chapter 5 quiz on Friday. Tomorrow I will address any and all homework questions during our shortened period; if any time remains, we will start chapter 6.

This weekend your homework will be to read chapter 6 (and take notes if you like); there will likely be a reading quiz on Monday.

Those of you at the Big E--first off, I hope you had fun! I know you're back a little later tonight, so you can all give me the assignment above on Friday (but no later!). Also, you need not complete the odds due today, as you should be doing the comparing boxplots activity/matching instead.

I'll be posting later with some model explanations in comparing boxplots; these are incredibly important for our quiz, so check back!

I'm back (it's 6 hours later, I swear, just edited this post). I've put our word document with each class' written response to compare boxplot in the "Powerpoints and Assignments" link. Check it out!

Monday HW

Today the onslaught of quizzes began...

Tonight, please complete page 90: 9, 12, 13, 17, 19

Here's a few announcements for the days to come:

Tomorrow's HW-->page 90: 15, 21, 23, 25, 27

We will have a quiz Friday on chapter 5. To prepare, we will have an after school review for this quiz as our second focused tutoring session on Wednesday after school (half day Thurs).

New students--I would like to meet Wednesday after school with each of you to cover any missed content/questions and get you up to speed. Please let me know when you're availabe so we can figure out a day we all have available.

Hope you all had/have a good Monday--back to the grind!

Weekend HW

Your only homework this weekend is to complete the chapter 3 take home quiz distributed this past Monday. For those of you already done, rest up, relax, and come back ready to get those minds working for another 5 days.

I've posted the take home quiz under our Powerpoints and Assignments in case you need another copy. You can find it titled, "Ch. 3 Take Home Quiz" (creative, huh?). If you don't have it Monday, you will earn a 0, no questions asked.

Although I am usually willing to answer any questions at any time via email, I may be less willing for this assignment (especially if you email me Sunday night). I gave you a full week to work on this so that you could look at it and use the time to get help.

Have a nice weekend everyone!

Thursday HW

Please complete the following 5 problems:

Page 90: 3,5,7,11,26

*You do not have to do any problems by hand. You can use a calculator for each.*

Also, remember your chapter 3 take home quiz is due Monday! There is no other weekend homework--just come back ready to work! (The onslaught of quizzes is coming....)

Someone asked for this via email, so check it out: steps for a boxplot:

Here are the stops to draw a boxplot:

1. Use your graphing calculator to find the 5 number summary (enter your data in L1, then press Stat-->Calc-->1 Var Stats)

2. Plot Q1, Median, and Q3 with a vertical line--these create the box in our boxplot.

3. Calculate the fences (these are the cutoff points for outliers) with the following formulas: Q1 - 1.5IQR and Q3 + 1.5IQR

4. Plot any outliers (values that fall outside these fences) with a dot.

5. Draw the arms (or whiskers) of your boxplot to the highest and lowest data values within the fences. **Students often mess up this step and draw the arms to the fence values--these are not part of our data, so this is incorrect**

Wednesday HW

I hate to say it, but I just realized that I don't have your problems at my home computer, so I don't have the chapter 4 problems due tomorrow. I hope you wrote them down in class. If someone sees this and could post a comment with the problems that'd be amazing. Maybe even a stamp for you tomorrow. Or, email me (fred.carofano@gmail.com) and I'll throw the problems up.

I know you have to do 4, 21, 22, and 35,

I'm really sorry guys. Check with a friend if you don't see a comment below.

Remember, your take home quiz is due on Monday. Tomorrow you're welcome to come work cooperatively after school and I can do some similar examples (but not the quiz questions) to help out. The more the merrier.

Hasta manana. Buenos tardes.

Monday Night HW

Here's Monday's homework...enjoy! (Def checking this one...)

Chapter 4 Exercises (page 64) 3, 9, 11, 19, 31

Friday!

Hope you're all ready to enjoy your weekend and get back to our first full week of school!

Hopefully you're feeling more clear after the day's discussion of independence. Remember, this will in fact be on your chapter 3 quiz Tuesday, so it might be a good idea to look at another example this weekend; that way, if you have questions, you can come after school Monday to have them clarified.

Your homework this weekend is to read chapter 4. Remember, you can take notes if you like, and if so, can use them on a potential reading quiz. It's our first chapter, so there's probably a good chance for one :).

Also, on Monday you will have a graphing calculator quiz--5/5 if you have one on your desk, 0/5 if you don't. No excuses. If you have an extenuating circumstance you should approach me before then in private (fred.carofano@gmail.com).

Enjoy the weekend! Watch some football. And keep an eye out for interesting stats we can use in class.

Here's an example for a nice answer when writing independence: Class and survival on the Titanic are not independent. Overall, approximately 32% of passengers on the Titanic survived. However, 62.46% of people in first class survived and 41.4% of second class passengers survived, showing both had a higher rate of survival. Both third class and crew had a much lower rate than the overall (the expected) rate of survival. According the data, the higher your class, the more likely you were to survive.

Thursday HW

Please complete:

Page 36 (Chapter 3): 19, 26, 33

**Period B** Notice I removed problem 39.

Wed. HW

Almost done with chapter 3....I cannot wait to start playing around with more numbers! We get a little taste tonight, with your Titanic homework. I've attached the activity under powerpoints and assignments if you lost yours.

Tonight please complete the Titanic/Independence activity. Make sure you do a thorough job. Think. Be creative. Use numbers, graphs, percents...tomorrow we'll base all of our discussion around these responses.

Tomorrow night we'll have some homework specifically about independence; this weekend I will most likely ask you to read chapter 4, and we'll have a quiz on chapter 3 next week (Mon or Tues).

Tuesday HW

Good work today! Well, B period at least. Other classes haven't happened yet.

Your homework tonight is page 39: 19, 23, 27, 37.

Tomorrow in class I'll check both this problem set as well as the weekend's (see below), and so you'll have a double homework grade (4 points rather than two)--so make sure it's done! We'll discuss any questions/comments/concerns and move onto Independence to wrap up chapter 3.

If you come across unfamiliar vocabulary in tonight's homework, I expect you to flip back through the chapter to find out what's being asked--I see this coming up with marginal and conditional distributions.

Enjoy!

Labor Day Weekend!

It was nice to get into some Stats today; I'm looking forward to playing with numbers and graphs and such quite a bit more as we move through next week.

Today we got into chapter 3 a little bit; if you'd like to review or get a little ahead, you can find the powerpoint under "Powerpoints and Assignments." On Tuesday we'll finish this up, and Wed we'll start working with independence.

Homework: problems 5,7,9,10,11,12 from chapter 3 on the handout provided in class.

Also, remember you have a QUIZ TUESDAY--probably only about 10 minutes, and similar to the discussion questions you did for homework. You will also be asked to identify quantitative or categorical variables. The answer key to your homework questions can be found in the same place as the chapter 3 powerpoint.

Other than that, enjoy your weekend! Once we come back it's the real grind...

First Day Homework

Tonight your task is as follows:

Read the "Cell Phone" and "SAT" articles and answer the 11 questions about each. Provide your best thoughts for each answer; if you are unsure about a question, do your best.

I'm working on uploading the articles and questions electronically, but the site is giving me problems at the moment...it'll be there...
