Do not, however, assume that this p-value, all by itself, tells
you much of importance with respect to whether or not there is a problem
analyzing these same data with a procedure which assumes that the
population of scores is normally distributed. The Shapiro-Wilk is quite
powerful, and will lead to significant results when the sample is from a
population not that far from normal.

Subject: Re: Need help - Shapiro-Wilk's W test...
If the p-level is below your "predetermined" level of significance, then
you would reject the null hypothesis that the data are a sample from a
normally distributed population...
