The main research method of this paper refers to the methodology adopted in completing the paper, including the selection of research objects, research design, data collection and data analysis. Correct research methods can effectively improve the quality and credibility of papers, which is an important basis for paper research. First of all, the choice of research object is the basis of this paper. The accuracy and scientificity of research object selection will directly affect the accuracy and scientificity of research results. The research object should choose a representative and reliable individual or collection of individuals related to the research problem. When choosing the research object, we can do it through literature review and field investigation, and we need to combine our own research direction, research purpose and research method to determine the research object.

Secondly, research design is a very important link in the paper research. The research design should be scientific and repeatable, and the experimental variables should be well controlled so that the research results can be copied by other researchers. Research design should follow the laws of scientific research, and determine research questions, research purposes, research assumptions, research methods, etc. At the same time, consider factors such as practical feasibility and research cost.

Data collection is an important part of this paper, and the quality and accuracy of data collection will directly affect the credibility of the research results. Data collection should conform to the research design and be carried out in strict accordance with data collection tools and standard operating procedures. Data collection should minimize errors and interference, and adopt scientific and effective methods to obtain accurate and reliable data. In the process of data collection, we should pay attention to controlling the experimental variables so that the research results can be copied by other researchers.

Finally, data analysis is an important part of this paper. Data analysis should choose the appropriate data analysis method according to the research purpose and problems, and process the data according to the requirements of data analysis method. In the process of data analysis, we should pay attention to data distribution, outliers, data correlation and other issues, and use scientific and effective analysis methods to analyze and interpret the data. Data analysis needs accurate and rigorous results, as well as credibility and repeatability.

In a word, the research method is the basis of the paper research, and the correct selection and application of the research method will directly affect the accuracy and scientificity of the paper research results. The coordination between each link determines the success or failure of the whole research. Therefore, researchers must strictly follow the requirements of research methods in order to obtain ideal research results.
