基于问卷调查的混合型数据处理方法

摘要

In order to extract comprehensive information, both qualitative and quantitative data were collected from com- prehensive survey. And how to process the mixed type data and construct an effective model are the most important prob- lems in questionnaire survey. In this paper,the model of quantification theory I is compared with multiple linear regres- sions by using the data from the English scores of a university class , and it shows that the former model is better.%在问卷调查时，为获取更详细信息，收集的数据一般既有定性的又有定量的。如何时混合型数据的加以处理，建立适当模型，是问卷调查中的一个关键问题。通过对某校大学生英语综合水平的考查，说明采用数量化理论I的方法进行模型拟合的效果比多元线性回归模型拟舍的效果要好。
