WebbIn most of the statistical tests, you need check assumption of normality. There is a test called Shapiro-Wilk W test that can be used to check normal distribution. If the p-value is greater than .05, it means we cannot reject the null hypothesis that a variable is normally distributed. SAS Macro for Normality
