This chapter describes the main tool used in the analysis of nominal and ordinal variables—contingency tables and discusses the different measures of association between the variables. Contingency is a fundame
1. Nominal variables: These represent categories without any inherent order. For example, survey questions about gender or ethnicity are nominal variables as they classify respondents into distinct groups.2. Ordinal variables: These not only categorize but also allow for an order or rankin...
In the context of categorical data analysis, the CATegorical ANalysis Of Variance (CATANOVA) has been proposed to analyse the scheme variable-factor, both for nominal and ordinal variables. This method is based on the C statistic and allows to test the statistical significance of the tau index ...
要区分nominal（定类变量）、ordinal（定序变量）、interval（定距变量）和ratio variable（定比变量），首先要理解它们各自的概念和用途。首先，定类变量，也称为nominal，表示变量的不同取值只代表不同类别的事物，比如人口调查中的“性别”就是一种定类变量。这类变量的值不具备数值大小的比较，它们的...

。2、计算方式不同：quantative是需要测量或者数出来的，qualitative是定义的，就像人物的性别不可能超越男，女两种是定义好的，收入的高低也是自己可以定义的实用文字分组的。3、定义不同：这两个都是variable中的形式，但quantitative是数量上的，而qualitative是性质上的，因此在使用时要注意区分。
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless. ...
