The first step is to understand the basic frontier knowledge and research results in the research field and have a full understanding of the research field.
We can understand the research status, research direction and research problems by consulting professional books, research papers and summarizing articles.
The second step is to determine the research problems and objectives, and clarify the research objectives and problems to be solved.
The research goal is usually to answer one or more related questions, such as "What are the risk factors leading to a certain disease?" , or "Is the new drug effective in treating diseases?" Wait a minute.
The third step is to collect data and information and establish research hypotheses.
Data and information can be collected from many aspects, for example, through interviews, surveys, experiments, literature reading and so on. At this stage, researchers can use the existing research results and data to establish hypotheses, or they can conduct preliminary research on the research object in order to establish hypotheses.
The fourth step is to establish research hypotheses based on data and information.
Research hypotheses are generally obtained through observation and thinking. When establishing a reasonable and scientific research hypothesis, we should pay attention to the following questions:
1. clarity of hypothesis: researchers should ensure that the hypothesis is clear, definite and easy to understand and test.
2. Operability: researchers should ensure that the hypothesis is operable, that is, measurable, quantifiable and repeatable.
3. Methods: Researchers should determine the research methods, techniques and data analysis.
4. falsifiability: Researchers should consider the hypothetical falsifiability. This means that the hypothesis can be proved wrong, so that researchers can constantly improve and perfect their own research.
To sum up, it is necessary to establish a reasonable and scientific research hypothesis through existing data and information. After completing the research hypothesis, researchers can start experiments and data analysis on the hypothesis, so as to confirm or overthrow the research hypothesis and further promote the development of scientific research.
