Hi. Im using Stata.

Im trying to conduct several analysis including t test and ANOVA. When i try
to perform normality analysis using shapiro wilk test it say that the data
is not normally distributed. But, when i perform shapiro francia test (with
the same data) it says that the are normally distributed...

Which of these results should I use (Wilk or Francia)?

Thanks in advance,
