Qualitative research and quantitative research
Qualitative research and quantitative research Connections:
(1) Both qualitative research and quantitative research belong to sociological methods. Qualitative research is mainly made cooked a expert noted the situation and the business based on personal intuition, experience, based on the study of past and present continuation of the situation and the latest information materials, the nature of the object of study, characteristics, changes of development to make judgments This method is to conduct research and judgment, put forward preliminary opinions, and then synthesize them as the main basis for predicting future conditions and development trends. Quantitative research refers to the use of modern mathematical methods to process relevant data, statistical data, establish various predictive models reflecting the regular relationship between relevant variables, and use mathematical models to calculate the various indicators and numerical values of the research object a way.
(2) Qualitative research is the basic premise of quantitative research, and quantitative research is the further deepening of qualitative research. It must be pointed out here that although qualitative research requires relatively low mathematical knowledge, there is no distinction between the two research methods, which is better and the other cannot be completely separated. In comparison, quantitative research is more scientific because it uses advanced mathematics knowledge, while qualitative research is a bit rougher, but this method has a wider application range and is suitable for general investors and economic workers because it is based on data. It is more suitable when the researcher’s mathematical knowledge is not sufficient or the researcher is relatively weak.
The difference between qualitative research and quantitative research
1. Different concepts
(1) Qualitative research means that researchers use historical review, document analysis, interviews, observations, and participation in experience to obtain educational research materials, and use non-quantitative methods to analyze them , Methods of obtaining research conclusions.
(2) The results of quantitative research are usually represented by a large amount of data. The research design is to enable researchers to make effective explanations through comparison and analysis of these data.
Different theoretical foundations
(1) Qualitative research is mainly a kind of value judgment, which is based on the humanistic methodology of hermeneutics, phenomenology and constructivist theories. The main point of view is that social phenomena are not dominated by causality like natural phenomena, and social phenomena are fundamentally different from natural phenomena.
(2) Quantitative research is a factual judgment, which is based on the methodology of positivism. Positivism originates from empirical philosophy, and its main point is: social phenomena are objective reality that exist independently, and are not subject to human will. In the evaluation process, the subject and the object are entities that are isolated from each other, and there must be inherent logical causality within and between things. Quantitative evaluation is to find, determine and verify these quantitative relationships.
