Given two or more sets of responses to categorical items ( e . g . , customer survey responses categorized as poor , fair , good , excellent ) , the six sigma black belt will be able to perform a chi - square test to determine if the samples are significantly different 给出两组或以上分类项目的响应结果（例如，顾客调查结果分类为差、一般、好、出色） ， 6西格玛黑带应能进行卡方检验以确定样本是否有显著差异。

Measurement of association rules correlation association rules generated by apriori algorithm includes some useless and even misleading rules . to gain more effective rules , a statistical criteria , chi - squared was used to measure the associations , furthermore the quantitative relations between the chi - . . 为了使生成的规则更有效，引入了统计学中的卡方检验从统计意义上检验规则是否关联，并找到卡方检验值与相关系数的数量关系，实现了两种方法的统一，并用基于相关系数的算法去生成关联规则。
The results indicate that : ( 1 ) mothers do more monitoring work in family : objective mother monitoring is higher than father , also are three monitoring methods ; ( 2 ) girls are monitored more than boys : objective mother monitoring is higher on girls than boys , and mothers also communicate more with girls ; both fathers and mothers use more control method on girls ; ( 3 ) there is not so much grade difference of parental monitoring , only that parents communicate more with grade 7 students ; ( 4 ) parental communication and control methods are both correlated positively with objective mother monitoring , but negatively with subjective mother monitoring , and solicitation method is just on the contrary ; communication method is the best positive predictor of objective mother monitoring , and solicitation method is the best positive predictor of subjective mother monitoring 经过( 2 )卡方检验、相关分析、 t检验和方差分析，结果表明： ( 1 )总体来讲，母亲在家庭里是青少年的主要监控者：母亲监控的客观水平高于父亲，并且母亲使用三种监控手段的情况均多于父亲； ( 2 )女孩受到的父母监控超过男孩：母亲对女孩的客观监控水平高于男孩，并且母亲对女孩更多使用沟通手段；父母对女孩使用控制手段的情况超过男孩； ( 3 )父母监控的年级差异并不明显，只有父母对初一学生会更多使用沟通手段； ( 4 )父母对沟通手段和控制手段的使用都与客观监控水平呈正相关，但与主观监控水平呈负相关，而搜寻手段使用与监控水平之间的关系则跟沟通、控制手段相反；沟通手段对客观监控水平的正向预测力最强，搜寻手段对主观监控水平的正向预测力最强。
First we analyzed the context and construction of the answers to the opened questionnaire to construct the coding handbook , then we receded these answers and used z - test and x2 test to analyze the conception of respect in children and its development . at last we studied the relationship between respect conception and friendships by t - test and anova 首先对收集到的小学儿童尊重观念问卷的开放式回答进行内容分析和结构分析，建立小学儿童尊重观念的编码手册，然后对儿童的尊重观念编码，运用z检验和卡方检验分析小学儿童的尊重观念及其发展规律，最后通过t检验和方差分析探讨尊重观念与友谊关系的各个层面的关系。
All algorithms are developed with visual basic and c . in the present paper a report is given of the results obtained the tests of independence , correlation and randomness which are involved parametric test , chi ~ square test , k ~ s test , correlation coefficient test , contingency table test and runs test 作者对产生的随机数进行了大量的检验工作。其中包括独立性、相关性、随机性的检验，涉及参数检验、卡方检验、 k - s检验、相关系数检验、列联表检验、游程检验等多种方法和形式。
Secondly , because behavior is the display of psychological actions , by noting down and anglicizing visitor behaviors , we can get the rules of visitors ’ psychological actions indirectly . this paper uses statistics method and spss software to analyze the survey date . in the past , most of the museum visitor surveys showed its results in the form of percentage and frequency 在分析方法上,本研究引入了统计学的分析方法和spss统计软件对资料作卡方检验、方差分析、线形回归等统计学上的分析,揭示不同性别、年龄、受教育程度、职业的观众在心理和行为上的不同特征,从而找出影响观众心理和行为的因素。
