1733年法国数学家狄莫弗首先发现正态曲线方程.以后,高斯和拉普拉斯都各自发现了这条曲线方程,所以正态分布也称“高斯一拉普拉斯分布”.正态分布是概率论中最重要的一种连续型分布,又是统计学的基石,因此具有独特的双重理论背景和应用价值.1教学现状《正态分布》是人教版高中选修教材2-3中的内容,被安排在第二章“随机变量及其分布列”中第4节,新课标要求“通过实际问题,借助直观(如实际问题的直方图),认识
In 1733, the French mathematician Demerfo first discovered the normal curve equation, and Gauss and Laplace later found this curve equation, so the normal distribution is also called the Gaussian-Laplace distribution. Normal distribution is the most important probability distribution in a continuous distribution, but also the cornerstone of statistics, and therefore has a unique dual theoretical background and application value .1 teaching status ”normal distribution“ is the PEP secondary school textbook 2 -3, which is arranged in Section 4 of Chapter 2, ”Random Variables and Their Distribution Columns,“ and New Curriculum Requirements ”through practical questions and intuitive (such as histograms of actual problems)
