This Nonlinear Modeling: Something Fishy lesson plan also includes:
There are plenty of fish in the sea, but only a few good resources on regression. Young mathematicians first perform a linear regression analysis on provided weight and length data for fish. After determining that a linear model is not appropriate, they consider how to transform the response variable or use a polynomial regression to identify a better fit.
