IDrawing a Scatter Diagram and xy Line Graph

The following procedure plots a scatter diagram and connects the dots to produce an xy line graph.

1.From the Main Menu, enter the STAT mode.

2.Input the data into a list.

3.Specify Scat (scatter diagram) or xy (xy line graph) as the graph type, and then execute the graph operation.

IDrawing a Regression Graph

Use the following procedure to input paired-variable statistical data, perform a regression calculation using the data, and then graph the results.

1.From the Main Menu, enter the STAT mode.

2.Input the data into a list, and plot the scatter diagram.

3.Select the regression type, execute the calculation, and display the regression parameters.

4.Draw the regression graph.
