The normal distribution is a continuous probability distribution that is bell-shaped and symmetric about the mean. This distribution is widely used in statistics due to its many desirable properties, including that it is well understood and can be described using only two parameters (mean and standard deviation). The chi-square distribution, F-distribution, mean distribution, and binomial distribution do not have these same characteristics and are not bell-shaped or symmetric.
