In part two of a three-part series, we meet Least-Squares Regression Lines. We learn how to use them to make predictions, how to interpret the slope/intercept of the equation, and the meaning and dangers of "extrapolation." Then, we define "residuals" and discuss how to calculate and interpret them in context.
