Normal distribution Definition, Examples, Graph, & Facts

normal distribution 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

The standard normal distribution table gives the probability of a regularly distributed random variable Z, whose mean is equivalent to 0 and the difference new normal The same is the case with standard normal distribution The difference between a normal distribution and standard normal distribution is that a normal
