Select two columns with paired number data in the spreadsheet, then click this tool to open a dialog that creates graphs and calculates two-variable statistics from the data. The dialog has four panels: a statistics panel, a data panel and two graph panels. Only one graph panel is visible when the dialog is first opened. Use the options menu to show the others.
The dialog opens with a scatterplot of the selected data. In the drop down menu below the graph you can select different regression models for the data. When a model is selected its graph is drawn on the plot and the equation is shown beneath.
