  1. Re-expressing Data: Get it Straight! Ch. 10

  2. What we’ve done What we’re going to do Use what we’ve learned about linear models to apply to non-linear relationships • Modeled approximately linear relationships with a linear model

  3. US Population

  4. Goals of Re-expression • Goal 1: Make the distribution of a variable more symmetric • Goal 2: Make the spread of several groups more alike, even if their centers differ • Goal 3: Make the form of a scatterplot more linear • Goal 4: Make the scatter in a scatterplot spread out evenly rather than thickening at one end
