Normality notes
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 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 … Ver mais 1. ^ Razali, Nornadiah; Wah, Yap Bee (2011).

Note that this definition makes an equivalent, and thus normality, a function of the chemical reaction. Although a solution of H 2 SO 4 has a single molarity, its normality depends on its reaction.
