Shapiro-Wilk Test Calculator

The Shapiro-Wilk test is a test for normality. The null hypothesis for this test is that the data are normally distributed. If the p-value of this test is less than your chosen level of alpha, then the null hypothesis that the data are normally distributed is rejected. If the p-value is greater than your chosen level of alpha, then the null hypothesis is not rejected.
