Analyzing Residuals (Part 2)

Learn about patterns in residual plots with an informative math lesson. Two examples make connections between the appearance of a residual plot and whether a linear model is the best model apparent. The problem set and exit ticket demonstrate ways to analyze a residual plot to determine if a data set has a linear or nonlinear relationship.
