一.概念 正态分布又称高斯（Gaussiandistribution），是统计学中一种最常见、最重要的连续型变量的对称分布，医学资料中有许多指标如身高、体重、红细胞数、血红蛋白、收缩压等频数分布都呈正态分布。频数分布逐渐接近正态分布示意图（若纵轴改为频率）正态曲线（normalcurve）图形特点：1.钟型 f(X)2.中间高 3....
Gaussian distribution:高斯分布,由数学家高斯提出,与正态分布相同,描述数据围绕均值对称分布的情况。 说明:高斯分布和正态分布是同一个概念的两种不同叫法,都用来描述连续变量的概率分布。 Bell curve:钟形曲线,因其形状类似于钟或倒扣的碗而得名,用来形象地表示正态分布。 说明:...

Normal distribution, also known as the Gaussian distribution, is a probability distribution that appears as a "bell curve" when graphed. The normal distribution describes a symmetrical plot of data around its mean value, where the width of the curve is defined by the standard deviation....
