Monday + Tuesday = Study!

1.) Your AP Classroom assignment has been assigned...

• The multiple choice (18 questions) is DUE WEDNESDAY at midnight and counts as a QUIZ GRADE!
• *I have not taught you how to work with re-expressed equations to make predictions--this shows up in question 16
• You may be able to figure this out depending on your past math experience, but maybe not--we'll look at this on Wednesday.
• Worst case, save this one until Weds. 
• The free response is just offered as a tool for you to use to study--this will not count as a grade!
• Just try the FR on separate paper and use the key below to check your work!
• Unit 2 Progress Check: Free Response KEY! (Click Me)

2.) STUDY! We have two tests coming up this week to start our quarter...let's prepare ourselves for success! 

• Wednesday = Vocabulary Test
• Part 1 = Matching (vocab list below)
• Part 2 = given a scatter plot identify the points with the most/least leverage, biggest/smallest residual, highest/lowest x or y values, identify outliers, and understand how points will affect the correlation, slope, and/or y-int
• Part 3 = write the equation of the LSRL given a computer output
• Vocab List:
• Scatterplot
• Explanatory Variable
• Response Variable
• Correlation
• Positive/Negative Association
• Lurking Variable
• y
• y-hat
• Correlation
• Know what does/does not change correlation
• Slope
• Y Intercept
• Coefficient of Determination/R^2
• Least Squares Regression Line (why is it called that/what does "best fit" mean)
• Outlier
• Influential Point
• Leverage
• Residual (formula, definition, what does it look like on a graph)
• Over/Underestimate
• Residual Plot
• Extrapolation
• Interpolation
• Thursday = AP Free Response and Multiple Choice Test
• Here's how to study:
• 1.) Complete the AP Classroom assignment
• 2.) Review all of your writing interpretations--this test will have a good amount of writing, but it's all stuff we've seen...
• Describe an association (reference r if possible)
• Is a linear model appropriate?
• Interpret Slope
• Interpret Y Intercept
• Interpret R^2 (coefficient of determination)
• Interpret the meaning of a residual
• Of course do this all in context!
• 3.) More practice problems you can use to study....
