Webb7 nov. 2024 · The Shapiro-Wilk test is a hypothesis test that is applied to a sample and whose null hypothesis is that the sample has been generated from a normal distribution. If the p-value is low, we can reject such a null hypothesis and say that the sample has not been generated from a normal distribution. WebbThe p-value is the probability of obtaining a test statistic (such as the Ryan-Joiner statistic) that is at least as extreme as the value that is calculated from the sample, when the data …
