Webnormality test procedures available in statistical software are the Shapiro-Wilk (SW) test, Kolmogorov-Smirnov (KS) test, Anderson-Darling (AD) test and Lilliefors (LF) test. Some of these tests can only be applied under a certain condition or assumption. Moreover, different test of normality often produce WebI was also looking on how to properly interpret W value in Shapiro-Wilk test and according to Emil O. W. Kirkegaard's article "W values from the Shapiro-Wilk test visualized with different datasets" it's very difficult to say anything about the normality of a distribution looking at W value alone. As he states in conclusion:

Die Faktorwerte liegen zwischen −1,706 und 1,527. Die Verteilung der Variable GF weicht von einer Normalverteilung ab (vgl. Abbildung 5 und Shapiro-Wilk-Test: W = 0,99, p < ,001).
WebRyan-Joiner normality test. This test assesses normality by calculating the correlation between your data and the normal scores of your data. If the correlation coefficient is near 1, the population is likely to be normal. The Ryan-Joiner statistic assesses the strength of this correlation; if it is less than the appropriate critical value, you ...
