- (Tomorrow (in class) you'll get an answer key to check these all out)
- Periods D, E, and H: skip #1b (or try to figure it out), we did not address this in class
- Period A you have a table we discussed that is used for #1b
Tomorrow in class we'll do some practice AP MC/FR in groups to finish up this unit and to prepare for the big day--TEST MONDAY!
Also, don't forget: Extra Credit HW + Stamps (Due Tomorrow)
- Complete AND SCORE the 2012 AP Free response on the back of Monday's HW paper....
- Score using a different color pen/pencil
- Here is the link to the scoring rubric:
- You will only earn extra credit/stamps if this assignment is completed AND scored (with notes/comments). If you do not score it and take notes on your scoring, nothing will be awarded.
- Scoring:
- Score each section (a, b, c) as E, P, or I AND provide bullets explaining why you got that score...
- If you earned a P, for example, write down notes about what you would need to add to earn an "E"
Today's Class Recap:
- Warmup......
- HW questions (from textbook)
- Finished Ch. 21 Notes:
- How does an alpha level relate to the types of error?
- How do the types of error relate to how we (would) choose an alpha level for a study?
- What is beta?
- How does changing alpha level affect beta?
- How can we decrease the probabilities of both types of error (alpha and beta)?
- What is power? How can we interpret power and how is it calculated?
- How can we increase the power of a test?
- Looked at an example for our notes....
Here's the worksheet for tonight's homework in case you need it:
