Linear relationships are examined in practically every discipline of the natural and social sciences. Using the statistics functions of the TI-83+/TI-84+ it is relatively easy to investigate this relationship by performing a linear regression on two variables, such as the following list:
Regression on the TI-84 (finding the line of best fit to the data) Enter the data into the lists of your calculator by pressing Se to get the list screen. Enter the data (x-values in L1, y-values in L2) Press `! to get the STAT PLOT screen. Press e and set up as shown. Press @ and set up appropriately Press S> to get this screen.

Regression modeling is the process of finding a function that approximates the relationship between the two variables in two data lists. To compute a regression model for your two-variable data on the TI-83 Plus, follow these steps: If necessary, turn on Diagnostics. When the Diagnostics command is turned on, the calculator displays the correlation coefficient […]
