WebA distribution is normal when the Mean, Median and Mode coincide together and there is a perfect balance between the right and left halves of the figure. But when the Mean, … 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, depending on one's interpretations of probability:
