How Do You Compare Data That Is Not Normally Distributed? When comparing two independent samples when the outcome is not normally distributed and the samples are small, a nonparametric test is appropriate. A popular nonparametric test to compare outcomes between two independent groups is the Mann Whitney U test. What do you do if your
How Do You Test For Normality In Statistics? The two well-known tests of normality, namely, the Kolmogorov–Smirnov test and the Shapiro–Wilk test are most widely used methods to test the normality of the data. Normality tests can be conducted in the statistical software “SPSS” (analyze → descriptive statistics → explore → plots → normality plots

Normality tests can be conducted in the statistical software “SPSS” (analyze → descriptive statistics → explore → plots → normality plots with tests).
How Do You Test If Sample Is Normally Distributed? For quick and visual identification of a normal distribution, use a QQ plot if you have only one variable to look at and a Box Plot if you have many. Use a histogram if you need to present your results to a non-statistical public. As a
