Binomial distribution and normal distribution
WebThe normal distribution is very important in the statistical analysis due to the central limit theorem. The theorem states that any distribution becomes normally distributed when the number of variables is sufficiently large. For instance, the binomial distribution tends to change into the normal distribution with mean and variance. WebApr 30, 2024 · The normal distribution is a continuous probability distribution that is symmetrical around its mean with most values near the central peak. ... For example, some tests such proportions tests (which use the binomial distribution) and the Poisson rate tests (for count data and use the Poisson distribution) have a form that uses a normal ...
