Probability Density Function (PDF) The general formula for the probability density function of the normal distribution is given by, where, μ is the location parameter, and σ is the scale parameter 2. Cumulative Density Function (CDF) WebbThe normal distribution is a continuous probability distribution for a real-valued random variable (X). It is symmetrical around the mean and its mean is also its median and mode . Due to its shape, it is sometimes referred to as "the Bell Curve", but there are other distributions which result in bell-shaped curves, so this may be misleading.

The parameters of the binomial distribution are p = 0.4 and n = 20 (for instance, we might take samples of 20 items from a production line when the probability that any one item will require further processing is 0.4). To fit a normal distribution we need to know the mean …

WebbA normal distribution is a type of continuous probability distribution. It is one of the most commonly used probability distributions, in part because many random variables with unknown distributions can be modeled using a normal distribution.
