Tonight, please complete the following in your textbook:
Page 160-167: 5, 11, 13, 19, 25, 29
- For 13a, to decide "is it appropriate to calculate correlation," check the following: is the scatterplot linear? are the variables quantitative? are there any outliers? If it's roughly linear with two quantitative variables and no clear outliers, then it's ok to calculate the correlation.
This homework assignment will give you a good idea of what's on our chapter 7 quiz! The chapter 7 quiz will challenge you to create a scatterplot and find r (using your calculator, like 19), describe an association (like 13b or 19), identify some errors in a statement about correlation (like 29), and identify one possible lurking variable (like 25b).
Here's our plan for the week with a crazy schedule (SAT day Wednesday, 1/2 day on Thursday...)
Tuesday: finish chapter 7 notes!
Wednesday: no class for period A; for periods E and F we will do some more practice with describing scatterplots; if you are in period A and don't have a class period E or F feel free to come by for some practice!
Thursday: Chapter 7 vocab quiz and chapter 7 "math" quiz (math quiz is based on your homework); then, we'll start chapter 8
Friday: Start chapter 8!
And I will have your unit tests for you by Thursday!
