Graphpad tests of normality
In statistics, normality tests are used to determine if a data set is well-modeled by a normal distribution and to compute how likely it is for a random variable underlying the data set to be normally distributed. More precisely, the tests are a form of model selection, and can be interpreted several ways, depending on one's interpretations of probability: WebDec 6, 2024 · Therefore, the use of non-parametric tests might be inevitable. 1.
