There are six commonly used methods: investigation and research, mainly including interviews, telephone surveys, questionnaires and so on. This method is to deeply and systematically understand the research object, collect a large number of data for comparison, analysis and induction, and thus summarize the regular content. The second method: observation and research refers to a way for researchers to explore the research object with their own senses and other auxiliary tools according to the research object, so as to obtain information. The third kind: experimental research method Experimental research method is the embodiment of a causal relationship between natural and social phenomena. Fourth, quantitative research method, also known as "statistical analysis method" and "quantitative analysis method", obtains the relationship, changing law and development of things by studying the quantitative relationship of the scale, speed, scope and degree of the research object, so as to achieve a correct understanding and prediction model of the research object. The fifth method: the simulation method (model method) is an experimental method that first designs a model similar to a certain phenomenon or process (prototype) in the laboratory, and then indirectly studies the regularity of the prototype through the model. Sixth: Exploratory research methods, using our known information knowledge, through our own exploration and innovation, get novel and unique theories and achievements. Note: writing a paper is not an easy task, nor can it be finished in a short time. In the process of writing, you must add your own ideas and opinions, and you can't copy others' achievements, so that you can write a good paper!
