WebbIn probability theory and statistics, the Normal Distribution, also called the Gaussian Distribution, is the most significant continuous probability distribution. Sometimes it is also called a bell curve. A large number of random variables are either nearly or exactly represented by the normal distribution, in every physical science and economics. Webb1 sep. 2024 · A theoretical distribution that has the stated characteristics and can be used to approximate many empirical distributions was devised more than two hundred years ago.
