WebbThe Shapiro-Wilk test is a statistical test used to check if a continuous variable follows a normal distribution.The null hypothesis (H 0) states that the variable is normally distributed, and the alternative hypothesis (H 1) states that the variable is NOT normally distributed.So after running this test: If p ≤ 0.05: then the null hypothesis can be rejected (i.e. the … WebbThe 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.
