Normality tests are statistical tests used to determine if a data set follows a normal distribution. They are used to assess whether a sample is drawn from a population that follows a normal distribution or not. These tests are used to check if the data is symmetrically distributed, if the mean and median are equal, and if the variance is consistent. Normality tests are important for determining the validity of a statistical analysis.

A Normality Test Calculator is a tool used to determine whether a given set of data is normally distributed. It is used to assess the probability that a given set of data follows a normal distribution. The calculator typically uses statistical tests such as the Shapiro-Wilk test, the Kolmogorov-Smirnov test, and the Anderson-Darling test to determine the normality of the data.

Normality tests are used to determine whether a sample of data is normally distributed. To calculate a normality test, you need to first calculate the mean, median, and standard deviation of the sample. Then, you can use a statistical test such as the Shapiro-Wilk test or the Kolmogorov-Smirnov test to determine if the sample is normally distributed. The results of the test will tell you if the sample is normally distributed or not.
