HSS.ID.B.6.b: Informally assess the fit of a function by plotting and analyzing residuals.
What you'll learn
- Define a residual as observed minus predicted and compute residuals for data points
- Construct a residual plot (residual versus x) with a reference line at zero
- Interpret a residual plot - random scatter signals a good fit, a pattern signals the wrong model
- Decide, from the residual plot, whether to keep the fitted model or refit with a different function family
