Normal Quantile Plots
The Normal Quantile Plot option
adds a graph to the report that is used

variable is normally distributed. If a
variable is normal, the normal quan-
tile plot is approximately a diagonal
straight line. This type of plot is
sometimes also called a quan-

The Normal Quantile plot also shows
confidence bounds. If the data fall
within these confidence bounds, the
data are approximately normal.
