WebNormality test. 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.

The following statistical tests compare the shape of the distribution to the symmetric normal distribution. The skewness test checks the symmetric level, the kurtosis test checks the distribution of the data over the tails and the middle, While D'Agostino-Pearson combines the skewness test and the kurtosis test, hence used as a normality test. citizenship interview test questions
