Wednesday: 3 Responsibilities

You have 3 things you're responsible for tonight and for our (likely) snow day:

1.) Study your chapter 13 vocab! You will have a chapter 13 vocab quiz in class the next time you see me (probably Friday)!

  • You defined each of the vocab terms in answering your chapter 13 reading questions over break!
  • There are 15 vocab words for this quiz!
  • Here's your vocab list: (some definitions provided in parentheses)
    • Experiment (method of data collection where we randomly assign treatments, only method that allows us to establish cause and effect)
    • Observational Study (no manipulation of factors, no assignment of treatments)
      • Retrospective Observational Study: observational study where existing data on the subjects' past behaviors/history is examine
      • Prospective Observational Study: observational study where subjects are identified, then data is collected over time/moving forward
    • Factor(s)
    • Level(s) (the values chosen for a factor)
    • Treatment(s)
    • Response Variable
    • 4 Principles of Experimental Design: (Control, Randomize, Replicate, Block)
    • Random Assignment (in an experiment treatments are randomly assigned to participants)
    • Control Group
    • Blocking
    • Blinding (when certain people--those receiving the treatments and/or those evaluating the results/collecting the data--are unaware what treatment group a subject was/is in)
      • Single Blind v. Double Blind
    • Placebo (used with our control group to help with blinding our experiment)
    • Confounding 
    • Matching (when subjects in an observational study are specifically paired and compared)
    • Replication
    • Control Group (a group that receives a baseline treatment or no treatment, often using a placebo)
    • Statistically Significant (when the differences/changes in the response variable are too noticeable to be caused by natural variation and are thus attributed to the changes in our factor)

2.) STAMPS are due at our next class!
  • Count your stamps!
  • Write the total on the front! Double check!
    • Your total must be correct! If I randomly select your name and double check your total and it's incorrect you will be given a 0 for your stamp grade.
  • Get these all together--put them in a bag, an envelope, staple them--somehow get these all together
  • If it's easier to rip a stamp off the corner of a paper than give the whole paper--do that! 

3.) STUDY, STUDY, STUDY for you Midterm! 
  • Today I provided you with an outline of the topics on our exam as well as a variety of additional practice problems you can use to study!
    • Answers to the stuff you got today in class will be posted on the blog (by Saturday)
  • You also have the documents I sent you via email--the 2015 midterm (practice exam)!
  • You can also use practice problems on sites like Khan Academy or using the sites linked on the right!
  • Check out this image for more ideas about how to study!
