Ch. 9 Vocab Quiz Tomorrow!

Tonight, STUDY FOR THE CHAPTER 9 VOCAB QUIZ! The vocab list is below! There are only a handful of new words on the vocab quiz--about half of them are repeated from our previous vocab quizzes!

Also, remember, STAMPS ARE DUE TOMORROW! Have them counted and ready BEFORE class! If you forget to turn them in tomorrow, or count them in class, you will have a 0 for your stamp grade!

Here's your chapter 9 vocab list for tomorrow's quiz:
  • Residual (3 definitions: the vertical distance between a point and the line of best fit, actual - predicted (or y minus y-hat), and measures "how far off" a prediction is--error)
  • Interpolation
  • Extrapolation
  • Outlier
  • Influential Point
  • Leverage
  • Lurking Variable (a variable that creates an apparent association between two variables; this is the reason we cannot determine cause and effect in an observational study)
  • Slope
  • Y-Intercept
  • Coefficient of Determination (R^2)
  • Least Squares Regression Line (the line that minimizes the sum of squared residuals)

And here's an extra credit (homework) opportunity for the second quarter based on today's classwork:
  1. Finish the 2012 AP Free Response Question we started in class. Be sure to do this on your own before you look at the rubric so you can accurately score it! If you just copy the answers and write down all E's, no extra credit!
  2. Then, score your free response question! Score each section as E, P, or I based on the rubric; if you score a P or an I, circle the components on the rubric that show why you got that score!
  3. Show me this on Monday!
