WebParametric tests are not very robust to deviations from a Gaussian distribution when the samples are tiny. If you choose a nonparametric test, but actually do have Gaussian data, you are likely to get a P value that is too large, as nonparametric tests have less power than parametric tests, and the difference is noticeable with tiny samples.
