Fitting Data with the TI-82 Tutorial
This tutorial teaches you how to use your TI-82 calculator to find linear, exponential, and power regression functions for your data - that is, 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).
The downloadable version is in Microsoft PowerPoint and is available in both Macintosh and PC formats. The download folder includes the PowerPoint Reader, which allows you to use the PowerPoint presentation on computers that do not have the full MS PowerPoint application loaded. The on-line version is nearly identicalto the PowerPoint presentation. Choose the format that best suits you.
