The null-hypothesis of this test is that the population is normally distributed. Thus, if the p value is less than the chosen alpha level, then the null hypothesis is rejected and there is evidence that the data tested are not normally distributed. On the other hand, if the p value is greater than the chosen alpha level, then the null hypothesis (that the data came from a normally distributed population) can not be rejected (e.g., for an alpha level of .05, a data set with a p value of less th… WebThe Ryan-Joiner Test is a simpler alternative to the Shapiro-Wilk test. The test statistic is actually a correlation coefficient calculated by. R p = ∑ i = 1 n e ( i) z ( i) s 2 ( n − 1) ∑ i = 1 n z ( i) 2, where the z ( i) values are the z -score values (i.e., normal values) of the corresponding e ( i) value and s 2 is the sample variance.
