Monday, Monday, Monday....

Everyone's favorite day of the week...back to work.

Tonight, please complete the following in your textbook: (starting some review homework so we're ready for that huge unit test when it comes...)

Tonight's HW:
Page 91: 41, 47

Page 131: 1, 3

Tomorrow we'll get into chapter 6--and I'm pumped!

Also, we will have a QUIZ THURSDAY (nothing new will be on it, but I want you to have 2 possible days to come after for help, Monday and Wednesday). The quiz will include the following:

1.) Create 2 boxplots WITHOUT your graphing calculator

2.) There will be some follow up question either asking you to compare the boxplots or interpret them in some way.

3.) Match 5 histograms to 5 boxplots.

It's the Weekend!

We made it to another weekend! Time is flying by...we're getting close the last chapter of our first unit even!

This weekend please complete the "comparing boxplots" problem regarding one of Charles Darwin's experiments. This is very similar to an AP style problem for this topic. The problem is on the back of the paper where wrote "your response" and then a "class response" about brainteaser completion times. If you can't find it, it's uploaded under our Classroom Resources entitled "Comparing Boxplots." Do page 2.

Enjoy your weekend! Monday we'll finish/start some multiple choice (for another grade) and then talk about standard deviation as we begin to move into chapter 6!

Thursday HW:

Hopefully you all did well on today's test! I'll try to get them all graded tonight!

Tonight, please create two boxplots--parallel boxplots are just two boxplots on the same axis, one above the other.

Given are 4th grade boys and girls performances on an agility test; the test asks them to jump from side to side across a set of parallel lines, counting the number of lines they can clear in 60 seconds.

Create parallel boxplots (one above the other) to compare the distributions of performances (number of lines cleared) for boys and girls.

Boys: 22,17,18,29,22,22,23,24,23,17,21

Girls: 25,20,12,19,28,24,22,21,25,26,25,16,27,22

**I would recommend you put the "boys" in L1, "girls" in L2, and then create parallel boxplots on your calculator--just turn plot 1 on and set it to a boxplot for L1, then turn on plot 2 as well and create a boxplot for L2. Hit ZoomStat, and you'll see the graphs--then transfer them to your paper and show the work for the fences!** (See page 80 for calculator help--it uses this exact same data!)



See you all tomorrow!

First Test Tomorrow!

Tomorrow is the day of our first test--so study, study, study!

Remember, you won't be doing any math or creating any graphs for the test--it's all about knowing vocabulary and concepts. There are 14 vocab words to match to 18 definitions (4 words have 2 definitions), worth 18 points. Then, there are 13 points worth of additional questions asking about different concepts (How does mean relate to median based on shape? What graphs are used for categorical/quantitative data? What are measures of center/spread? And how can we define shapes?)

Good luck! Email me if you have any questions about definitions (or anything else test related)!

Tuesday HW

Tonight, please complete the following in your texbook:

p. 92: 13, 17, 27, 29, 35

Back to work!

Boxxxplottttssssss. Yes.

We will have a vocabulary test on the chapters we have covered thus far on our half-day, Thursday. Study, study, study! This is your first TEST grade in AP Stat!

Check out the list to the right for the vocab words!

As for tonight, please complete the following homework assignment:

p. 93: 19, 24, 31 (save 35 for tomorrow!) 

Enjoy! See you all manana! (just visualize the ~)

PS...if you'd like to get a head start, here's tomorrow's homework:

p. 92: 13, 17, 27, 29, 35

It's the Weekend!

Enjoy the weather today and tomorrow, and do your homework Sunday while you're watching the Giants and it's raining...

Here's your weekend homework (you too period F!):

page. 91: 3 (do it all on your calculator), 5 (skip commenting on Sx and IQR), 7a-c, and 9 (for this question, to think about which has a larger standard deviation, just choose which data set has "more spread").

And....page 131 6ab.

So that's 5 problems for this weekend! Not too bad!

Period F--don't forget about your AP problem also (see the post below for some more info).

Also, if those of you in period F want a stamp, you can write down 5 EHHS-related goals you have for this year. They might include academics, extracurricular, or social activities, but must be school related. AND, they have to be in COMPLETE SENTENCES.

Back to School Night!

I'm looking forward to meeting some parents, guardians, siblings, aunts, uncles, etc. tonight. Hopefully yours is there!
Tonight, please complete the 2007 AP problem provided in class.

Remember, for part B you have to describe SOCS (just turn the stemplot to its side to see the shape). And, when you describe center and spread, you should calculate the mean, median, and find the range using the data and your graphing calculator--we don't need to "eyeball" the median, we can actually calculate it!

For part c, consider the mean and median you calculated. Consider why these numbers would be misleading as reports of center, given the distribution of the data.

Then, check your answers with the link below:

And tomorrow's Friday! Woop!

**Period F: All seniors will be at an assembly about texting and driving. You will STILL have homework. And some catching up to do.**

Hump Dayyyyyy

In case you didn't watch last time....

Tonight, please describe the distributions for the four histograms provided in class. All answers should be written in complete sentences and should be thorough. Remember--you need to describe SOCS, and keep everything in context!

Here's a sample answer we drafted in period E for number 1. You can use this as a guide:

The distribution of the duration of Old Faithful eruptions is bimodal and roughly symmetric, with no apparent outliers. The median duration was approximately/about 3.5 to 4 minutes; the range of durations was about 4 minutes. Most eruptions either lasted under 2.5 minutes or over 4 minutes.

2's Day

Histogram quiz tomorrow! Make sure you can create a histogram (with the aid of your calculator) and answer questions based on reading the histogram (as discussed today in class)! If you were absent, talk to someone who was in class today--because you're still taking the quiz tomorrow!

For those of you who are at the Big E--have a blast! You'll have to make up the quiz when we return.

Tonight, please complete the AP Free Response question provided in class (year 2000, #3).

Remember, this is different than any histogram we've created thus far--you are given the frequencies to create 2 histograms (one for middle-aged, one for young men). Then, compare!

You can check your answers here: (just look for #3)

Back to Work!

Hopefully  you all enjoyed the beautiful weekend--now it's back to work!

Tonight, please complete the following in your textbook:

Page 65: 3, 4,7,23, 35

Good luck!

And make sure you know how to make a histogram--ideally, first create it on your calculator, and then transfer this graph to paper. Practice, practice, practice!

Weekend HW

It's supposed to be a beautiful, cool, fall weather weekend--get outside and enjoy it! Go to the game tonight and support your classmates as well! I'll have to wait until the next home game (tonight is a friend's birthday).

This weekend, please complete the following:

For each of the following four problems, please create a histogram. Then, in 2 complete sentences, describe what you see in the graph (the distribution). Try to provide one sentence that gives a general statement about what the graph tells us about the given context; then, add a second sentence providing some specific support/data that you can read from the histogram.

The data you will use can be found on...

Page 67: 17, 19, 21, 22 (all histograms!)

Feel free to email with any questions.

It's important that you practice doing these both by hand AND using your graphing calculator. For calculator help check out page 54-55 in your book, or use the link to the right (Using Your Graphing Calculator).

I've also updated the powerpoints (sorry about that Sandra).

Enjoy the weekend! See you Monday! (hopefully with good news about your quiz grades) :)

Thursday!

Tonight, please complete the chapter 4 reading questions provided in class. I'll get them posted a little later. I'm looking forward to grading today's chapter 3 quiz! Hopefully you're confident you got an A!

Sorry for the lame post, I'm on my phone...

Quiz Tomorrow!

Study, study, study! Get an A on your chapter 3 quiz tomorrow! Remember, it'll cover categorical displays, probability questions using contingency tables, and independence--you've seen everything on it. There won't be any surprises.

Tonight, please complete questions 17 and 31 in the chapter 4 exercises.

Good luck! Looking forward to tomorrow!

Stay cool! It's 35 million degrees out!

Two's Day Homework...

Great work today on independence! We have lots of great posters hanging around the classroom with a variety of graphs and two main approaches to the problem--let me know if you want to take a poster home to hang on your bedroom wall.

Tonight, please complete the following:

Page 65: 11a, 14a, 19a, 21a

For three of these you need to make a stemplot, and for one a dotplot--we haven't discussed this in class yet. I expect you to use your resources (textbook, the blog, the internet...) to help if you're stuck! Do your best!

Tomorrow we'll get into quantitative displays and summaries--lots of numbers!

Finally, don't forget we have a quiz on categorical displays and independence on Wednesday! Study! (it shouldn't take the entire period...)

Monday...back to work!

Tonight, please complete the following:

Page 39: 21, 27d

Both of these deal with the idea of independence; continue to think about the Titanic problem we began looking at today as you do your homework. Tomorrow you'll have about 15 minutes to get to work with your groups and finish your posters before we discuss!

We will have a chapter 3 quiz on Thursday. We will start chapter 4 on Wednesday, but I wanted to give you an extra day to come after school (Weds) in case you have any questions!

It's the weekend!

Enjoy the beautiful weather this weekend! Do your Stats outside again!

This weekend, please complete the assignment provided in class regarding Categorical Data Displays. I've uploaded this under our classroom resources, entitled "Categorical Data Displays." This will be collected and graded! Don't forget about it!

Be sure to be thorough in your writing; use complete sentences!

In addition, please complete #37 on page 39--a problem that shows Simpson's Paradox.

Thurssssday

Hey.....you.......go outside and do your homework if the sun's out!

Tonight, please complete the following in your textbook (to be checked tomorrow):

Page 39: 7, 13, 14, 17

Enjoy! More chapter 3 notes tomorrow! :)

Wednesday HW

My school computer's still acting silly about this whole blog thing...

Anyway, tonight's homework is...

p. 39: 5, 9, 19, 22a-c, 23a-e



Enjoy! Be ready to take LOTS of notes on chapter 3 tomorrow (and go over any homework questions of course)!

I really hope you read this...

Sorry for the little-bit-late revision to this blog post--for some reason my computer at school has been temperamental with the blogspot site. Let me try all this again...

So I'm adding two problems to those assigned tonight; this complete assignment will be check in class on Thursday. But don't forget--your syllabus needs to be signed/returned by tomorrow!

Homework Problems Due Thursday:
p. 39: 5, 9, 19, 22a-c, 23a-e


Tomorrow, we'll start class with a short, 10-point quiz on context. Then, you'll get the first AP Statistics pre-test (so we can generate some data and see how much we've learned)!

On Thursday/Friday we'll quickly move through some chapter 3 notes...be ready to learn! Our goal is to be starting chapter 4 next Monday!

Enjoy your evening!

If you haven't seen this, watch it. And you'll probably be doing this all day tomorrow.
