TEST TOMORROW!

Any outstanding/missing/late homework assignments from the past week can/must be turned in by TOMORROW for credit. ALL homework must be graded using the keys on the blog for credit. (See past blog posts for each assignment). 

STUDY FOR TOMORROW'S TEST! How, you ask?

1.) Complete your take home test!

• Collecting Data Take Home Exam
• Use your notes, textbook, and other resources! Take advantage of this opportunity to start the quarter with a strong test average!
• There is especially NO reason to get any of the vocab matching wrong!

2.) Be sure to look over/use all of the FR/MC/Examples we've completed in class this past week to prepare for our test!

3.) Know your vocab (and other stuff to know for the test):

• You should definitely read the sample responses from Friday's FR linked below
• Check out the bottom of this blog post for some notes/examples from Weds-Fri
• Be sure you know how each sampling method is conducted (stratified, cluster, SRS, systematic, census)
• Also be able to write a detailed procedure for a sampling method!
• What is bias? + be able to describe bias, in context (like the 2013 FR HW)
• Types of bias: know the 4 types and their definition
• Population v. Sample
• Experiment v. Observational study? Know how to recognize each (like the Method I/II FR from Thurs. night)
• Know why we stratify--advantage of a stratified sample
• Choose a variable to stratify by and explain why
• For experimental design:
• Explanatory Variable, Response Variable, Experimental Units, Treatments
• Know how a blocked experiment works (same idea as stratifying, just a different name)
• Choose a variable to block by and explain why (again, same idea as stratifying, just a different name)
• Know how to randomly assign treatments for an experiment (write a procedure)
• Blinding--know what it is! Look at that "ultrasound" HW we had...

Extra Credit FR (due Tuesday because I forgot to collect it today):

• You can complete question 2 (on the back of last night's homework) for extra credit!
• AP Classroom FR
• You must have the correct answers for extra credit!
• Part A = create a segmented bar graph!
• The "relative frequency" is the same as the "%" (look at how the y axis is labeled numerically)
• Part B = math question!
• Use proportional reasoning to determine how many people we should sample that said "yes" if we're sampling from the 300 ppl who said "yes" or "no."
• Your answer is a #! "_____ people."

Notes/Resources for Weds-Fri:

• Friday: we completed the 2011 FR (linked below) in class; take a look at some sample answers too!
• All of you should definitely read this!
• Sample Responses for 2011 FR! Read this!
• Thursday: we completed the linked classwork assignment; this was collected and graded. If you were absent, use the notes below to complete this and turn it in tomorrow. You can print it or write your answers on separate paper.
• ID Types of Bias and AP MC
• Here are Thursday notes--definitions for each type of bias:

• Here is another resource we used Thursday--definitions for the "parts of an experiment" and the example from our midterm exam--this is definitely something to use for Tuesday:

• And here are our examples from Wednesday's class/discussion/note: writing about bias
