Normal Quantile Plot

Note: This module requires a column of data that is already listed in the STATDISK data window

If the column of data is not already in the STATDISK Data Window, close this window and enter or open data sets so that they are listed in columns of the STATDISK Data Window. (To open a data set from Appendix B in the textbook, click on "Datasets" at the top. To manually enter a data set, click on Data, then click on Sample Editor. The data can also be copied into STATDISK from another application, such as Minitab or Excel.)

Select the column to be used for the normal quantile plot. The default is column 1. To change the column, click on the small box to the right of the default value of 1, then scroll down to the desired column and click on it.

Click on the Plot button to obtain the normal quantile plot.

The labels (coordinates of the individual points) can be included or excluded by clicking of the "Turn on labels" or "Turn off labels" button near the bottom.

The graph of the regression line can be included or excluded by clicking on the box next to "Regression line" near the bottom.

Click on the Print button to print the results.

To close the window, click on the X at the top of the module window.
