Monday = Study and HW!

Tonight you have two responsibilities for homework:

1.) Complete questions 1 and 2abc on the "Experiments Wrap Up: Blocking" worksheet provided in class.

2.) STUDY! We will start class tomorrow with our chapter 13 vocab quiz! (Then it's back to probability!)

Here's the chapter 13 vocab list (with some definitions):

1. Experiment (treatments randomly assigned)
2. Observational Study (no manipulation of factor--no assignment of treatments)
3. Retrospective Observational Study
4. Prospective Observational Study
5. 4 Principles of experimental design (what are the 4?)
6. Factor (the IV, the explanatory variable, the variable we manipulate in an experiment)
7. Levels (the specific values of the factor)
8. Treatments (the "groups" we create--if there is one factor the levels = the treatments; if there are multiple factors, each factor has its levels, and the treatments are all of the different "overall" groups we create)
9. Response Variable (the data we collect--what we're measuring in a study)
10. Random Assignment (where does it happen in an experiment?)
11. Control Group (a group that receives a baseline treatment, typically a placebo, used for comparison)
12. Replication
13. Blocking 
14. Blinding (single v. double blind)
15. Placebo
16. Confounded/Confounding Variable
17. Matching (this is when the subjects in an observational study are paired based on some characteristic--we are specifically pairing two data values)
18. Statistically Significant

Here are the homework questions tonight in case you lost your paper or were out:

Suggested Midterm Review HW:

• Complete 2011 (Form B) #2 and/or the 2009 Free Response #3 provided in class (or linked below)
• (ALWAYS) Score your response--this will allow you to check your understanding, and it will also give you some insight into how I will be grading your midterms!
• Link to ALL released FR and Scoring Rubrics: CLICK ME!
• Go to 2011 Form B and/or 2009 and click on "Free Response Questions," the scroll to the appropriate number to find the question
• 
  
• Choose the "scoring guidelines" (for the appropriate year) to see the scoring rubric--scroll down to #5 for the suggested HW

Today's Class Recap: (slightly varies by period)

• Stamp = midterm review (unit 1 stuff)
• Blocking Discussion


• What is blocking? Why do we do it? (generic notes)
• Discussed blocking in relation to our homework and our Carofanogrow context
• Discussed the "which blocking scheme (A or B) is better? Explain." question found in our slides
• Discussed 2007 (Form B) Free Response #3, focusing on question A
•
