The Normal plot is a graphical tool to judge the Normality of the distribution of sample data.
Select or enter the variable's name in the variable input field. Optionally, you may enter a selection criterion in order to include only a selected subgroup of cases in plot. When you have completed the dialog box, click the OK button to proceed.
The horizontal axis of the Normal plot shows the numerical values of the observations, and the vertical axis gives the relative frequency in terms of the number of standard deviations from the mean.
A straight reference line represents the Normal distribution. If the sample data are near a Normal distribution, the data points will be near this straight line.
Probably a Normal distribution
Probably not a Normal distribution
