- AP Stats Guy Videos (Unit 2)
- Study/review your chapter 8 take home quiz
- Use the multiple choice provided on Monday in class (or at the bottom of this post) to practice
- Use the multiple choice provided today after our test for more practice (see below)
- Review your notes
- Be sure you know how to interpret slope, intercept, R^2, describe an association, and determine if a linear model is appropriate
Here's breakdown of what's on the test:
Thursday's Test: AP Free Response and Multiple Choice: You will use a graphing calculator throughout all of Thursday's test. This test will include AP multiple choice and free response questions. Here's a breakdown of the content:
- Use a linear model to make predictions
- Determine how a point that is added/removed may affect slope, y-intercept, and/or correlation (r)
- Calculate a residual given a linear model and an actual value
- Use a re-expressed linear model to make a prediction
- Use the 4 multiple choice questions provided in class today to practice this! See below...
- Given a residual and linear model, find an actual value
- Identify a point with the highest/lowest residual or most/least leverage
- Determine if a linear model is appropriate for a given data set
- Describe an association shown in a scatter plot
- Interpret slope
- Interpret y-intercept
- Interpret the coefficient of determination, R^2
- Interpret the meaning of a negative/positive residual
- Determine if you are confident in a prediction (based on interpolation/extrapolation)
- Bonus: find the equation of a linear model algebraically
- *See the extra credit question on our chapter 8 take home quiz about "height vs. minutes played"
- The formulas for slope and y-intercept will be provided
And here are the two multiple choice from today that deal with topics covered on tomorrow's exam--the answers are circled in red so you can check!
