I Drawing 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.

I Drawing 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.
