Thursday/Friday HW!

**AP REGISTRATION FORMS DUE TOMORROW!**

If you were out today you must make up the quiz tomorrow during lunch/study/start of class OR at the start of class Monday!

You have two homework assignments, both of which will be checked on Monday:

1.) Complete AND SCORE the 2013 AP Free Response #2. (technically Thursay's hw)
  • You will only be given credit if you complete the FR, score it, AND write a few notes/bullets explaining why you got the score you did...anything else will earn a 0!
    • For example, if the rubric says you would earn a "P" (partially correct), then provide some notes that explain what you would've needed to add to earn an E!
    • Here is the link to the scoring rubric:
    • For part a:
      • Question A asks how using the first 500 students who enter the football stadium to estimate the % of students who are satisfied with the appearance of the school's buildings might be biased....
      • We have not talked about bias yet, but you got this...
      • Write about the following for a:
        • 1.) Why might the sample not represent the population in regards to feelings about the appearance of buildings/grounds? More so, what types of students (in regards to feelings about appearance of buildings/grounds) might be over (or under) represented with this sample?
        • 2.) How does this connect to estimating the % (proportion) of students who are satisfied with the appearance of the buildings/grounds--would you expect this sample to over or underestimate this %? (connect back to your ideas from step 1 above)
2.) Complete the "Ch. 12 HW: Identifying Sampling Methods" questions/worksheet provided in class (or below).
  • Check your answers! (posted tomorrow)
  • GRADE YOUR HOMEWORK! Learning is about making mistakes, then using a sample solution to work backwards and figure out those mistakes you made! Learning is not about "getting it right on the first try," or just doing your homework and never checking your work!
Here are the questions you can do (tonight) based on what we learned in class today (Thursday):
  • 2013 Free Response #2: part a (read above), part b (complete and score)
  • Ch. 12 HW: #13b, 27a, maybe 27b
    • For 13b you are asked "what could go wrong with the design." Remember, we're trying to collect a sample that represents the population, so consider how such a method may lead to a sample that does not represent the population it is supposed to

Today's Class Recap:
  • Quiz! (see the practice quiz from yesterday's post)
  • AP Registration forms due tomorrow!
  • Chapter 12 Notes: Sampling (lots of vocab)
    • Sampling Vocabulary:
      • Sampling Variability
      • Sample Size (not based on the size of the population!)
    • Intro to sampling methods...
      • Introduced "bodies of water" context
      • Why do we (have to) collect random samples?
      • Worked together to develop a procedure for a simple random sample
      • Tomorrow we'll work through the remaining sampling methods!
