3. Calculating and Graphing Paired-Variable Statistical Data (Curve Fitting)k 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 Statistics mode.

2. Input the data into a list.

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

Press A, J or !J(QUIT) to return to the List Editor.

Example

Input the two sets of data shown below. Next, plot the data on a scatter

 

diagram and connect the dots to produce an xy line graph.
