### Normal
Distribution of Residuals - Normality Plot of Residuals

To check for meeting
the assumption that the residuals or error terms are normally distributed, we
look at the Normal p-p plot of Regression Standardized Residual as shown below:

Our criteria for
normal distribution is the degree to which the plot for the actual values coincides
with the green line of expected values. For this problem, the plot of residuals
fits the expected pattern well enough to support a conclusion that the
residuals are normally distributed. If a more exact computation is desired, we
instruct SPSS to save the residuals in our data file and do a test of normality
on the residual values using the Explore command.
