TI-82,83 Data Fitting Tutorial—An Overview

What should this tutorial help you do with your TI-82,83 Calculator?

• After completing this tutorial, you will be able to:

• Enter, graph and manipulate data relating two variables

• Find linear, exponential, and power regression functions for your data—that is, find the linear, exponential or power function that best fits the data (in the sense of minimizing the sum of the squares of the vertical deviations of the function graphs from the data points).

• Determine how well a regression function fits the data points by statistical as well as graphical means.

• You will do all this in an interactive context involving some interesting real data on stomach and lung cancer.
