WebThe Shapiro–Wilk test is a test of normality. It was published in 1965 by Samuel Sanford Shapiro and Martin Wilk. ... values of the order statistics of independent and identically … Web6. In general when the number of samples is less than 50, you should be careful about using tests of normality. Since these tests need enough evidences to reject the null hypothesis, which is "the distribution of the data is normal", and when the number of samples is small they are not able to find those evidences.

Web12 de mai. de 2014 · Chi-square Test for Normality. The chi-square goodness of fit test can be used to test the hypothesis that data comes from a normal hypothesis. In particular, we can use Theorem 2 of Goodness of Fit, to test the null hypothesis: H0: data are sampled from a normal distribution. Example 1: 90 people were put on a weight gain program.
