为更好的让学生理解统计知识中二项分布中样本率的变化规律及演变过程,掌握其频率变化的总体规律,利用EXCEL办公软件的相关功能,编制二项分布趋向于近似正态分布条件的演示程序;适用于不同参数设置条件下二项分布的概率分布展示,极大提高课堂教学效果。
In order to better enable students to understand the changing law and evolution process of sample rates in the binomial distribution of statistical knowledge and to master the general rules of frequency changes and make use of the related functions of EXCEL office software to formulate the binomial distributions that tend to approximate normal distribution conditions The demonstration program is suitable for displaying the probability distribution of binomial distribution under different parameter setting conditions and greatly improves the effect of classroom teaching.
