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)!

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:

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.
