In statistics, pi is used in the equation to calculate the area under a normal distribution curve; which comes in handy for figuring out distributions of standardized test scores, financial models, or margins of error in scientific results.

在统计学中,π 可代入等式中用来计算正态分布曲线下的面积;在计算标准化考试分数、财务模型或科学结果的误差范围时都会用到。

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)。

若随机变量X服从一个位置参数为\mu、尺度参数为\sigma的机率分布,记为:

Normal distribution 正态分布

(重定向自Normal 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.
