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, … Ver mais An informal approach to testing normality is to compare a histogram of the sample data to a normal probability curve. The empirical distribution of the data (the histogram) should be bell-shaped and resemble the normal … Ver mais Tests of univariate normality include the following: • D'Agostino's K-squared test, • Jarque–Bera test, • Anderson–Darling test, • Cramér–von Mises criterion, Ver mais One application of normality tests is to the residuals from a linear regression model. If they are not normally distributed, the residuals should not be used in Z tests or in any other tests … Ver mais Simple back-of-the-envelope test takes the sample maximum and minimum and computes their z-score, or more properly t-statistic (number of sample standard deviations that a sample is above or below the sample mean), and compares it to the 68–95–99.7 rule: … Ver mais Kullback–Leibler divergences between the whole posterior distributions of the slope and variance do not indicate non-normality. However, the ratio of expectations of these posteriors and the expectation of the ratios give similar results to the … Ver mais • Randomness test • Seven-number summary Ver mais 1. ^ Razali, Nornadiah; Wah, Yap Bee (2011).

In general, assuming normality is plain wrong, a random variable could be whatever (exponential, Pareto, beta, gamma). In the same sense if you have some data it could be that they come from a particular distribution or that they are "random" or deterministic.
