Based on four tests ( simple t test, wilcoxon rank test, pair wise test, and binomial test), we find that the average correlation coefficient within the family is significantly higher than the correlation coefficient between the family and outside families.

通过两总体均值检验（t检验），Wilcoxon秩和检验，配对检验以及Binomial检验等四种方法，我们发现家族内基金的平均相关系数显著高于家族间基金的平均相关系数。

Overall these students rank in the 21st percentile on the tests─that is, they did worse than 79 per cent of all children taking the test.

这些考生的总体百分位排名占第21位。就是说，79%的应试儿童比他们考得好。

By an example to show the conclusion in rank test will be changed to the test of hypothesis for some key data fluctuate random and small.

本文用实例指出，在两组秩和检验中，某些关键数据的随机性微小波动可改变假设检验的结论。

Object Evaluation of the comparative methods of independent samples: Mest, u-test, Satterthwaite method, Cochran-cox method and Wilcoxon rank-sum test, offers some information for statistical analysis in practice.

目的对完全随机设计两样本比较常用方法t检验、u检验、Satterthwaite法，Cochran-cox法和Wilcoxon秩和检验等方法进行评价，为实际工作中统计方法的合理选择提供参考和依据。

And the weaker condition of hybrid system observability and rank test rules are given. An illustrative example is given at last.

Application wilcoxon sign rank test, X2 test, t test and correlation analysis statistical test.

应用wilcoxon符号秩检验、X2检验、t检验及相关性分析进行统计检验。

When sample size is large enough, Mest, u-test, Satterthwaite method, Cochran-cox method and Wilcoxon rank-sum test are all recommended.

在两样本含量均较大时，t检验、u检验、Satterthwaite法，Cochran-cox法和Wilcoxon秩和检验等方法相互替代是可行的。
