几类教育现象的统计分析

Statistics Analysis in Several Kinds of Educational Phenomena

通过编制频数分布表、计算均值、方差、标准差、进行正态分布的拟合度检验及对成绩差异情况检验等过程,用正态分布的性质分析两个班的成绩及两班学习成绩的差异情况,说明了数理统计在教育教学中的应用方法。同时,通过分数转换、定录取线、量化等级等例子,对数学的价值和发展趋势做出了科学的分析和评判。

In this paper, I introduce some applications of mathematical statistics in teaching appraisal,and working out frequency distributions table, computing mean value, variance, standard deviation. By the process of testing the fitness of Normal Distribution and checking mark difference, etc. , and using the character of Normal Distribution to analyse two classes＇s mark and its difference, we get some conclusions. At the same time, by some examples of fractional change, customize matriculate line, quantify grade, we analyse and judge the value of teaching and the evolution trend, etc.
