Het volgende voorstel voor de legend van Shapiro-Wilk, bijna letterlijk uit de EN689 Annex E
Legend:
Shapiro-Wilk:
If p (normal) > p (lognormal) it may be concluded that a normal distribution fits the results better than a lognormal distribution (EN689 Annex E)
The power of the test to reject (log)normality is too limited for the small sample numbers considered here
