The rationality of arithmetic mean being the best representative is demonstrated by the introduction of relevant judging axiom.
通过引入判定公理 ,证明了算术平均(数)为最佳代表的合法性 ,分析了变异指标判定算术平均(数)代表性的方法 ,同时指出通过标准差变异系数判别 ,分析其理论存在的缺陷及缺陷发生的情况 ;进而分析了通过平均指标衡量算术平均(数)代表性的方法 ,并就判别定理适用范围进行了分析。
As the arithmetic mean is easily affected by the extreme data, present method of giving a mark collectively by judges can not always reflect most of their opinions.
由于算术平均(数)易受极端数据的影响,现行由评委集体评选计分的方法,往往不能反映大多数评委的意见。
In this paper, a simple rule for the harmonic mean and the arithmetic mean was given.
给出了应用调和平均数与算术平均(数)的简单规则 。
The relation between arithmetic average and harmonic average is described, which is one of the difficult problem in statistics, and a good approach of the difference between arithmetic average and harmonic average is provided.
文章对统计学中的难点问题算术平均(数)与调和平均数的关系,特别是其区别做了探讨,找出了区分的较好方法。
The relationship of three collect current index-meddle,mode and arithmetic average is discussed in this article and the author explains that three of them are affected by their symbol value and frequency and their places are indefinite.
探讨中位数、众数、算术平均(数)三个集中趋势指标在平均数中的关系,说明它们的大小是受其标志值和次数的影响,其位置是不确定的。
This paper demonstrates that the quantitative relationship among arithmetic average, mode and medium, which is widely described by the teaching material of principal of statistics is not correct.
本文通过大量例子证明统计学原理教材中所描述的有关算术平均(数)、中位数和众数三者的数量关系是不正确的，因而反映总体偏斜程度的算术平均(数)与众数比较法，偏态系数是不合适的。
