REGRESSION Linear Regression (Page 1 of 8)

For a given set of data points, the line that "best" fits the data as a model is called the least-squares regression line. The TI-83 or TI-84 can easily compute the equation of this model. Consider the following data:

x 3 4 5 6 7
y 8.9 12.6 16.7 20.0 24.6

This data consists of five ordered pairs. Before entering the data using the stat editor, we will first ensure the stat editor is set up properly. This is done with the SetUpEditor command from the Home screen.
