Stefania,
you might also want to double-check results by using 'exact'
tests or by bootstrapping statistics and their ASE obtained
from the nonparametric tests applied.
If your sample distribution is heavily skewed or tied, even
non-parametric tests can deliver misleading results.
Best regards, Marcus
