Normal distribution theory
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: Web24 de abr. de 2024 · From these basic statistics we can construct the test statistics that will be used to construct our hypothesis tests. The following results were established in the section on Special Properties of the Normal Distribution. Define Z = M − μ σ /√n, T = M − μ S /√n, V = n − 1 σ2 S2. Z has the standard normal distribution.
