Qualitative research refers to discussing and studying problems from a theoretical perspective and putting forward countermeasures and suggestions without specific figures. If combined with examples, we can do an empirical study.

This kind of quantitative research is to design the questionnaire and related indicators in combination with practical problems, and then conduct statistical econometric research or mathematical model research on the data collected from the questionnaire according to a certain mathematical model, so as to draw biased opinions according to the calculation conclusions of the data model.

Of course, both methods can be used when doing the problem, but the most important thing is that through this study, we will analyze the method of doing the problem.
