You can use the Plots tab (Figure 17.4) to create a histogram and a normal Q-Q plot of the chosen variable.
If you select , then the histogram includes an overlaid normal curve. (See Figure 17.5.) The parameters for the normal curve are the location and scale estimates of the data. A vertical reference line in the
            histogram indicates the location estimate, and shading indicates regions more than 
 units from the location estimate, where 
 is the scale multiplier and 
 is the scale estimate.
