Shapiro wilk normality test vs kolmogorov

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 … 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.
