TEST TOMORROW!

We have a HUUUUUUGGGGEEE two days coming up in AP Stat--two days of tests to cap off our Linear Regression unit!

• Wednesday's Test = Matching Vocab and AP MC
• Thursday's Test = AP FR and MC 

Tonight, STUDY, STUDY, STUDY! 

• I will also be here tomorrow (Wednesday) after school if you'd like to study for our test Thursday!

Here's an outline of what's on TOMORROW'S TEST:

• Vocab List (matching):
• Explanatory Variable
• Response Variable
• Outlier
• Leverage
• Influential Point
• Residual (graphically, how it's calculated, what it measures)
• Lurking Variable
• Predicted Value (y-hat)
• Slope
• Y-Intercept
• Coefficient of Determination (R^2)
• Correlation
• Least Squares Regression Line (LSRL)
• Re-express data (coming Monday)
• Scatterplot
• Residual Plot
• Overestimate
• Underestimate
• Extrapolation
• Interpolation
• Actual/Observed Value (y)
• Short Answer Section:
•  You are given a graph with points labeled A-E and asked which point has the highest/lowest leverage, highest/lowest residual, highest/lowest x or y value, etc.
• Multiple Choice Section:
• Interpret slope
• Interpret y-intercept
• Interpret R^2
• Predict using a re-expressed model (covered in class Monday/Tuesday)
• Determine how a point will influence r, slope, y-int (like Thursday's classwork)
