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:

WebNormal Distribution. The normal distribution is described by the mean ( μ) and the standard deviation ( σ ). The normal distribution is often referred to as a 'bell curve' because of it's shape: It is symmetric, meaning it decreases the same amount on the left and the right of the center.
