1, survey method
Investigation is one of the most commonly used methods in scientific research. It is a purposeful, planned and systematic method to collect materials about the actual situation or historical situation of the research object. Generally, a large number of data are obtained by answering questions in writing or orally, and then a large number of data collected in the investigation are analyzed, compared and summarized to provide people with regular knowledge.
2. Observation method
Observation is a scientific research method that people systematically investigate the objective things in the natural state through the senses and auxiliary instruments in a purposeful and planned way to obtain empirical facts.
3. Experimental method
Experimental method refers to a research method which is carefully designed, under the condition of high control, by manipulating some factors, to discover the causal relationship between variables, so as to verify the predetermined hypothesis. The core is to properly control the conditions of the object to be studied and eliminate the interference of irrelevant factors in the natural state.
4. Quantitative analysis method
Quantitative analysis is a research method for quantitative analysis of things or their components. According to the statistical data, the mathematical model is established, and the indexes and their values of the research object are calculated through the mathematical model. Common quantitative analysis methods include ratio analysis, trend analysis and mathematical model method.
5. Qualitative analysis method
Qualitative analysis is the qualitative analysis of the research object. By means of induction and deduction, analysis and synthesis, abstract generalization, etc., the obtained materials are processed by thinking, and the internal laws of things' operation are revealed, including causal analysis, comparative analysis and contradiction analysis.
6. Empirical research.
The application scope of this method is second only to the literature method, which shows that it is deeply loved by teachers and students. Its main function is to clarify the relationship between independent variables and a dependent variable, such as logistics, finance, economic management, accounting, psychology and so on.
7. Case analysis method
This research method is juxtaposed with the literature method, empirical research method and the most commonly used research methods in the three major papers. The three methods are often used, and the role of case analysis is very extensive, including pedagogy, psychology, management, finance, accounting, statistics, law, logistics and other majors. Through case analysis, ask questions, analyze problems and solve problems.
8, fuzzy mathematics method
This method is used to analyze, judge, reason, suggest, make decisions, control and budget the results of papers. This method is mostly used in hospitals, mathematics, petroleum geology, environmental science and other science and engineering majors. It looks difficult.
