WebbThe Shapiro-Wilk test is a statistical hypothesis test used to determine if a given data set is normally distributed or not. This test is widely used in various fields, including finance, … Webb27 jan. 2024 · The Tests of Normality table contains two different hypothesis tests of normality: Kolmogorov-Smirnov and Shapiro-Wilk. Kolmogorov-Smirnov (K-S) is a nonparametric test. It technically can be used to test if the data come from a known, specific distribution (not just the normal distribution).

This test also performs the Shapiro-Francia normality test for platykurtic samples. Cite As Ahmed BenSaïda (2024). WebbThe most common analytical tests to check data for normal distribution are the: Kolmogorov-Smirnov Test. Shapiro-Wilk Test. Anderson-Darling Test. For the graphical test either a histogram or the Q-Q plot is used. Q-Q stands for Quantile Quantile Plot, it compares the actual observed distribution and the expected theoretical distribution.
