Chapter 3: Fitting Functions to Data

In this chapter you will learn how to use your grapher to find the best-fitting linear function for a given set of data and how it adapts this technique to fit other types of functions. You'll see how you can calculate the correlation coefficient, and you'll learn ways to find the type of function that is most appropriate for a given set of data. You'll apply the techniques you learn to problems such as predicting the increase of carbon dioxide in the atmosphere, a phenomenon that leads to global warming.
