Law of normal distribution
Did you know?
In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is $${\displaystyle f(x)={\frac {1}{\sigma {\sqrt {2\pi }}}}e^{-{\frac {1}{2}}\left({\frac {x-\mu }{\sigma }}\right)^{2}}}$$The … Meer weergeven Standard normal distribution The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when $${\displaystyle \mu =0}$$ Meer weergeven Central limit theorem The central limit theorem states that under certain (fairly common) conditions, the sum of many random variables will have an approximately normal distribution. More specifically, where Meer weergeven The occurrence of normal distribution in practical problems can be loosely classified into four categories: 1. Exactly normal distributions; 2.
