常态分布德语:Normalverteilung英语:normal distribution)又名高斯分布德语:Gauß-Verteilung英语:Gaussian distribution, 以德国数学家卡尔·弗里德里希·高斯的姓冠名),是一个在数学、物理及工程等领域都非常重要的机率分布,由于这个分布函数具有很多非常漂亮的性质,使得其在诸多涉及统计科学离散科学等领域的许多方面都有着重大的影响力。比如图像处理中最常用的滤波器类型为Gaussian滤波器(也就是所谓的正态分布函数)。

Normal distribution 正态分布

(重定向自Bell Curve)
For the normal distribution, the values less than one standard deviation away from the mean account for 68.27% of the set; while two standard deviations from the mean account for 95.45%; and three standard deviations account for 99.73%.
As the number of discrete events increases, the function begins to resemble a normal distribution

In probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.
