| Nov 23, 2020 at 21:34 | comment | added | TrungDung | How large the sample size? It says here that "if the sample size is sufficiently large this test may detect even trivial departures from the null hypothesis (i.e., although there may be some statistically significant effect, it may be too small to be of any practical significance)" en.wikipedia.org/wiki/Shapiro%E2%80%93Wilk_test. | |
