The property of a data set or random variable of following a normal (Gaussian) distribution. A Shapiro–Wilk test was used to assess the normality of the sample data.
In mathematics, the condition of an object such as a subgroup, ring, matrix, or algebraic variety being normal. The normality of the subgroup is essential for constructing the corresponding quotient group.
