Webb5 juli 2024 · Table 2 shows that the Shapiro-Wilk test is the best among the four normality tests because it has the lowest sum of ranks. It is closely followed by the Kolmogorov-Smirnov test and the Anderson-Darling test. Chi-square goodness-of-fit test has the largest sum of ranks and hence the poorest. WebbThere are two common normality tests: the Kolmogorov-Smirnov (KS) and Shapiro-Wilk test. The Shapiro-Wilk test is preferred for small samples (n is less than or equal to 50). For larger samples, the Kolomogrov-Smirnov test is recommended. However, there is some debate in the literature whether the “50” that is often stated is a firm number.
