高中数学新教材“选修 ”中借助于总体密度曲线的概念 ,对正态分布的意义进行了介绍 ,指出在实际中常见的服从正态分布的随机变量 ,并直接给出正态分布的主要性质 ,进而说明了统计中常用的假设检验基本思想 .本文就本人的教学实践体验浅谈“正态分布”这一节课程内容的教学 .1
The concept of the overall density curve is used in the elective of the new high school mathematics textbook. The significance of the normal distribution is introduced. It is pointed out that in practice, random variables that follow the normal distribution are given, and the main properties of the normal distribution are given directly. The basic ideas of hypothesis tests commonly used in statistics are explained. This article discusses the teaching of “normal distribution” in this part of my teaching practice experience. 1
