WebbIn addition, when the normality tests examined in all distributions were taken into account and compared, it was concluded that the Shapiro-Wilk gives better results than other tests in general for normal and non-normal distributions, and that D'Agostino -Pearson, Skewness and Jargue-Bera tests were also stronger than the other tests. WebbFor both of these examples, the sample size is 35 so the Shapiro-Wilk test should be used. For the skewed data, p = 0.002 suggestingstrong evidence of non-normality. For the approximately normally distributed data, p = 0.585, so normality can be assumed and provided any other test
