What are qualitative research and quantitative research?

Qualitative research is another main method of exploratory research. Researchers use qualitative research to define problems or find solutions to them. When looking for ways to deal with problems, qualitative research is often used to make assumptions or determine the variables that should be included in the research. Sometimes qualitative research and second-hand data analysis can form the main part of research projects. Therefore, it is necessary for researchers to master the basic methods of qualitative research. Quantitative research is to seek the quantitative representation of data and adopt some form of statistical analysis. Generally speaking, when considering a new research project, it is usually necessary to conduct appropriate qualitative research before quantitative research. Sometimes qualitative research is also used to explain the results of quantitative analysis.
