Qualitative research is a research method that establishes a conceptual system, deduces logically with the help of theoretical paradigm, explains hypothetical propositions accordingly, and finally draws theoretical conclusions. In typical qualitative research, we don't use statistical analysis, but get rich information through literature research, field observation and in-depth visit to the research object. Common qualitative analysis includes observation method, unstructured interview method and life history method (that is, describing the life course of someone or some people according to diary, autobiography and other materials). ) and literary criticism. The basic operation steps of qualitative research are: exploratory research stage, the main work is to get some preliminary concepts from the collected data; In the definition stage, based on the concepts formed in the early stage, the researchers worked out several groups of variables that fully reflected the connotation of these concepts; In the reduction stage, the obtained data are screened, and the core theory or conclusion of the research is formed on this basis; In the whole stage, the researchers have comprehensively and organically expounded the proposed concepts and theories, and verified these concepts and theories one by one with data.
Quantitative research is a research method that uses mathematical statistics and computer-aided means to measure the variables to be analyzed in the research object, and uses mathematical models to statistically analyze the relevant data to verify the hypothesis. The commonly used quantitative analysis methods include field investigation, controlled experiment and content analysis. As far as quantitative research is concerned, its scientific procedure is to choose research topics and put forward research hypotheses; Design research schemes and measuring tools; Collect information; Collate and analyze data; Write a research report.
