Thursday HW = Ch. 21 Wrap Up!

Tonight please complete the "Ch. 21: Types of Error" worksheet provided in class (or below) to wrap up chapter 21.
  • (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:
