Experimental research must include: experimental design, experimental operations, data analysis and result inference to verify the correctness and reliability of hypotheses and research results.
Before conducting experimental research, the following aspects must be met:
1. Research questions and hypotheses. The premise of experimental research is that a research question and hypothesis are needed, that is, the problem and research object to be studied are determined, and the research hypothesis is designed. The research questions should be clear, specific, and practical, and the research hypotheses should be verifiable and can be studied and verified using experimental methods.
2. Experimental design and experiment
Operation. Experimental design is a key step in experimental research. It is necessary to determine a series of experimental elements such as the experimental object, experimental group, control group, and experimental conditions, as well as experimental operating procedures and methods to ensure the controllability and repeatability of the experiment. Experimental operations need to be carried out in accordance with the experimental design and implemented in strict accordance with the experimental procedures.
3. Data collection and data analysis. Experimental research requires the collection and recording of data generated during the experimental process, and subsequent data processing and analysis. Data collection should be precise, systematic, and comprehensive, and data analysis should be conducted based on statistical methods based on the experimental design and research hypotheses.
4. Research results and conclusions. Experimental research obtains research results through experimental operations and data analysis, and draws research conclusions through statistical analysis and inference. The research results and conclusions are required to be accurate, reasonable, repeatable, and capable of further theoretical analysis and exploration.
5. Experimental safety and ethical issues. Experimental safety and ethical issues need to be observed during experimental research. The safety of experimental operations should be given sufficient attention, and risks that may arise during experimental operations require risk assessment and preventive measures. At the same time, experimental research needs to follow scientific ethical principles and respect the rights and interests of research subjects and the basic dignity of human beings.
In summary, experimental research must have important contents such as research questions and hypotheses, experimental design and operations, data collection and analysis, research results and conclusions, and experimental safety and ethical issues. These contents require strict planning and preparation before the experimental research is carried out to ensure the reliability, repeatability and safety of the experiment.
