Today we started our last big topic of the year.
CW:  Ch. 20 #10
HW:  Ch. 20 #9

Tuesday, Feb 13th

Well folks, here's the end of Ch. 19:  #8, 23 and 25.
Make sure and show me some work on #23 and 25!!!

FRIDAY!!!

Today we learned how to put a frequency table into our calculator.  (two lists).
Then we learned that you can graph it and find all the stats.  This is a handy tech tip that is not required, but might come in handy for the AP test.  Especially in Chapter 16, where the expected value and standard deviation formulas can take lots of calculator work, this tech tip can be useful. 

There will be an extra credit question on our next test regarding this topic.

If you want to read about this TI-Tech Tip go to:

**Page 43, last paragraph
**Page 68, last paragraph
**Page 313, the whole Tip

There are now two posts that say "Wednesday".  22, 24 and 28 and the article is for Thursday, due Friday.

Thursday--a little help

22a)  13.7%
22b)  31.9"
22c)  What's shape?  ______
What's the mean?  _____
What's the sd? ______ (hint:  something divided by the square root of something)
22d)  0.005

24a)  skewed right--you can't stay for less than zero and a few people will stay a long time.
24b)  The CLT will guarantee normality for large sample sizes.  For individuals, we don't have a clue how to calculate probabilities for skewed distributions.

28a)  4.78%
28b)  (1 - 0.0478)^3 = 0.863
28c)  Like 22c above...
28d)  Basically zero

Finish worksheet
Compare and contrast types of graphs learned about this year and their uses.

Friday

After we took the make-up regression quiz, I assigned this problem:

1978—63,042

1979—226,260

1980—907,075

1981—2,826,095

Year vs. acres devastated by the gypsy moth.

 

Please do this:

2)       Take log(acre) to linearize

3)       Graph and describe year vs. log(acre)

4)       Find LSRL, write it down in context.

5)       Graph resid and interpret

6)       Make a prediction for 1982

Test tomorrow!

Study for your regression test tomorrow.  Study Wednesday's worksheet.  You could also use your taxi test for a useful study guide.  You could also use the list of problems I assigned last week before we took the taxi test. 

Good luck!

Article #4 due tomorrow

Thursday

We did a great little vocabulary crossword puzzle today.  I will stamp the review on Monday, but you obviously want to finish it tonight.  I also noted that there are two typos on the review.  The last line should be 5 d, 15c, 17ef, 27g.

Happy studying!  See you all tomorrow!

Wednesday

Today we took a normal quiz and I passed out a list of review problems for Friday's test.  The review sheet contained this information:

Here's some review for regression.  Hopefully, nothing is surprising here.  LSRL's, r, R^2, residuals, slope and y-intercept.  You should know the drill by now.  There are three different ways you can find the equation of the line, so after warming up with sofa, your first 3 questions go over those 3 methods.  I recommend you do these problems in the order they are listed.  They are all odd, so if you're self-disciplined, you can get some good review done and check your work as you go.

 

Unit 2 review (p204…)

• correlation/sofa: #1, 17a
• Write the equation:  #3c, 5a, 27c
• Use the equation!: 5bc, 27def
• r & R^2:  #7acd, 27ab
• residuals:  #5c, 15c, 17ef, 27c

Tuesday

What can r tell you?  Not much without a picture!

Discussed quiz
Ch. 5 #5ab
Ch. 5 #27ab
Ch. 5 #35

Homework:
Ch. 5 #6, 7, 12, 19, 36, 41

Good Answer #14

      4-cylinder is skewed to the left, 6-cyl. is skewed right and 8 is symmetrical.

      4-cyl has a median around 32, 5-cyl. and 6 are at 21, 8 is even lower with a median mpg at around 18!

      The 4 cylinder has more variation, the 6 and 8 have less variation.  The IQR's are:  7, 4 and 2, respectively!

Note that the 6-cylinder has an outlier and there is only 1 car with a 5-cylinder engine.

Good Answer #13

Here's a good answer for Ch. 5 #13:

Both male and female distributions are skewed to the right.

Males have a median around 24, while females marry much younger at a median age of around 21!

The middle 50% of men goes from 23 to 26, while the middle 50% of women goes from 20 to 23.

The IQR of both groups is about 3!

The men marry so much older than the women, the third quartile of the women is about the first quartile of the men!

Ch. 4 #19, 20, 28

Thursday & Friday

On Thursday we took notes on Shape, Center & Spread from pages 39-42.  This vocabulary is crucial to CUSSing.  We also learned how to make a histogram on our calculator.  You can read the TI Tip in chapter 4 to help you with this.  Don't forget the TI Tip on page 11 is the first step in the process.

In class we have CUSSed for: 

• The sibling dotplot
• Ch. 4 #5
• Ch. 4 #7

We described the stemplot for Ch. 4 #11 (McGuire) and we hand-made a stemplot for #13

Homework for the weekend:  Ch. 4 #4, 6, 8, 12, 14

Sept. 6th

We took some very important notes about CUSSing:

Center
Unusual Features
Shape
Spread

We will explore this more on Thursday.

Project Part 2

Exploring the Data

Due Friday, June 2nd

This section should be an outstanding example of exploratory data analysis (the first unit in our text, chapters 3, 4 & 5).  Graphs should show the comparisons between all relevant groups you are comparing.  You should state any preliminary conclusions that can be drawn by using your eyeballs.

• Graphs of your data
• Statistics from your data
• Descriptions of the graphs and statistics.
• Extra Credit for using DataDesk!

Correction

Oopps! That is, chapters 12 for surveys and chapter 13 for experiments!

Project--Data Design

Due TOMORROW! MLA format
oDescribe how you collected your data (at least 1 paragraph).
oDescribe what biases you think you successfully reduced.
oDescribe what biases you do not think were reduced successfully.
oUse the proper vocabulary from chapters 13 and 14!!

ELM

Hey geniuses!

If you are taking the ELM, you should study!  Here are two web sites to help you out:

http://www.sa.sdsu.edu/testofc/elm_guide.html

http://library.csus.edu/guides/rogenmoserd/hall/mathtest.html

Last Minute Tip #3

**Read the whole problem (a, b, c...) BEFORE you start it.  Often times the pieces of the problem will be connected.

**Pick a side and defend it.  Don't ride the fence!

**If a problem says use TWO things to justify, make sure and use them BOTH!  If a (c) says, use (a) and (b), use them both!  If you are choosing between two options, don't just say why you like the one you choose, also state why you DON'T like the other.

Good luck!
