分布函数及其应用简析

A Brief Analysis of Distribution Function and Its Application

分布函数是《概率论与数理统计》中重要的内容之一,从分布函数的定义出发,深刻揭示泊松定理、正态分布的标准化定理等内容的实质,借助数学建模的思想强调以分布函数为基础的计算问题,最后以学生考试成绩分布图刻画分布函数的直观含义。

Distribution function is one of the important contents in Probability Theory and Mathematical Statistics.From the definition of the distribution function,the essence of the Poisson’s theorem and the normalized theorem of the normal distribution is deeply revealed,and the calculation problem based on the distribution function is emphasized with the aid of the thought of the mathematical modeling,and the visual meaning of the distribution function is also characterized by the distribution function of the students.
