normal distribution Normal distributions come up time and time again in statistics A normal distribution has some interesting properties: it has a bell shape, the mean and If a set of n observations is normally distributed with variance σ2, and s2 is the sample variance, then s2σ2 has a chi-square distribution with n–1 A normal distribution is completely determined by its mean μ μ and its standard deviation σ σ , which means there are an infinite number of normal distributions
