Is it possible to determine non-linear relationships between variables? For example, in the Mammals Sample Data Set, I plotted Lifespan vs Mass. This is a non-linear relationship. Is it possible to determine the equation for the curve?
CODAP doesn’t have any curve fitting capabilities (beyond linear). Of course it’s possible to fit a curve from a chosen family by setting up a slider to vary, and computing squares of residuals whose sum can be minimized, but this is a lot of work.
