Chapter 8 Linear Regression

Writing and analyzing the line of best fit for a set of quantitative data.

Special focus needs to be given to the MEANING of the slope, y-intercept and value of r squared on each problem.

Notice the relationship between r and the slope of the best fit line and the relationship between the line and the mean of each variable.

We will spend about six class periods on this chapter. Some problems to do:

By Monday 10/29,  read to page 175, do #1-7

 Classwork Distance and Ticket Prices due Mon 11/5
Investigative Task: Report on Smoking due Tues 11/6

By Friday 11/9 do ch 8 #8,10,12,14, 15,17,19, 28-30, 32, 41, 47,48

Friday: Unit II Exam (ch 7, 8)

We will be getting into this concept soon in class, but it is so applicable now that you really need to read it.

Ch 7

Start in with ch 7, read and do problems 1-10 odd and 6. We will finish this chapter in a week, having the quiz next Wed. The 24th.
We will do most of the odds, so if you want to go beyond the first assignment, do those.  Focus on THINK, checking conditions. Then TELL, describe scatter plots in terms of direction, form, strength, and unusual features.
important vocabulary: association, correlation, explanatory ( or predictor) and response variables.

Don't forget: MAKE A PICTURE!

Further problems:
11-21 odd, 18
23-33 odd, 24, 26, 34

Quiz on Wed 10/24

Ask each other (and me) questions on Unit 1 stuff!

here is place to ask, answer, help and aid each other :)

Test Info

Welcome to Mrs. Schmitt's AP Stats Class

This is where we will help each other by asking and answering questions, posting some required responses, etc.
Don't forget to do the packet, read ch 1, ch2 and do every third problem in ch 2 by the first day of school. I suggest you not wait until the last minute for this. There will be a quiz on the first day, covering this material.

Other than that, have a fun summer!

If anyone brings in examples of statistics in media, I might give you some extra credit!
