- You can also check out the AP Stats Guy Videos--Unit 5 Videos #6, 7, 8, 9 if you need some help or missed some class time!
- This take home quiz is a great summary of what you need to know about chapter 19 thus far!
Juniors/people who were out Friday: here's what you missed:
- We DID NOT get to the stamp problem I gave you (juniors)--so don't worry about doing that! (That will be our stamp on Wednesday)
- We start class by looking over a key for last night's homework--use this example/key (posted below) to check your homework and as an example!
- In class we completed and scored the 2017 AP Free Response! Please get this done to best prepare yourself for success!
- Here is the homework key:
- Here is the 2017 FR question:
- And here is the link to the 2017 Scoring Rubric so you can check your work and score your FR:
When we return next week we'll finish up chapter 19 (Weds-Fri), and then we'll start the following week with some quizzes (vocab and math quiz).
Here are some of the topics we're going to explore next week--feel free to read ahead in chapter 19 or do some independent research to get a head start!
Chapter 19: Topics for Next Week...
- Understanding margin of error...
- What is margin of error?
- How does changing sample size (increasing or decreasing n) affect ME?
- How does changing n affect the width of an interval?
- How does changing our confidence level (increasing or decreasing C. level) change ME?
- How do changes in our C. level affect the width of the interval?
- What is a point estimate?
- How can we find the value of a point estimate (sample statistic) given only the interval?
- How can we find margin of error given only an interval?
- What does __% confidence mean?
- Interpret confidence LEVEL--we know how to interpret the interval, now we have to discuss how to interpret the level
- How can we find sample size for a given margin of error?
- How can we use an interval to "test a claim?"
- We've done this! This was like #13d from our homework, deciding if our interval supported/contradicted a politician's claim that 1 in 5 auto accidents involved a teenage driver
Feeling ambitious? Here is a textbook homework assignment for when we return:
- I'm not sure when I'll assign these, or if I'll split them into multiple assignments, but at some point when we return we'll have to complete these textbook problems:
