Normal distribution mean standard deviation

The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when and , and it is described by this probability density function (or density): The variable has a mean of 0 and a variance and standard deviation of 1. The density has its peak at and inflection points at and . WebNormal distribution probability density function is the Gauss function: where μ — mean, σ — standard deviation, σ ² — variance, Median and mode of Normal distribution equal to mean μ. The calculator below gives probability density function value and cumulative distribution function value for the given x, mean, and variance:
