NOTES
Fitting data is another inductive problem. Here is some data - if we want to control the response (Y-axis) we need to figure out what the relationship between the control (X-axis) and the response is (at least here I'm assuming we've got a pretty good idea which variable is control and which is response - the control is the variable you can change by adjusting a knob or something like that).
We want to come up with a theory that allows us to get the response we want using the control. But how do we do that, and how do we make sure we've done it right?
