分类资料也称定性资料,是与定量资料相对的。定量资料本身数据简单,但分析方法繁多;分类资料数据类型虽多,但分析方法较少。分类资料主要有3种:二分类、无序多分类和有序多分类。不同类型的数据有时可用相同的方法来分析。分类资料组间比较方法的选择可以考虑以下几点。①设计类型:是完全随机设计还是配对设计?②结局指标的类别:是二分类还是多分类?是有序还是无序?③比较组数:是两组还是多组?根据这些一目了然的条件,可以选择相应的分析
Classification information, also known as qualitative data, is relative to quantitative data. Quantitative data itself is simple, but the analysis of many ways; classification data types of data, but less analytical methods. There are three main categories of information: two categories, disorderly multi-classification and orderly multi-classification. Different types of data can sometimes be analyzed in the same way. The classification of data between groups to choose the method of comparison can consider the following points. ① design type: is a completely random design or paired design? ② outcome indicators of the categories: is the classification of two or more? Is ordered or disorder? ③ Comparison of groups: two or more groups? Based on these clear conditions, You can choose the appropriate analysis
