The normal distribution is another name for the bell curve probability distribution. The normal probability density function (PDF) is
![{\displaystyle f(x)={\frac {1}{\sqrt {2\pi \sigma ^{2}}}}\exp \left[-{\frac {1}{2\sigma ^{2}}}\left(x-\mu \right)^{2}\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/f2b67030f8d9591101d98e243d62c69376859105)
