Different:
Qualitative is to describe it in written language. It is a method that mainly relies on the analyst's intuition, experience and subjective judgment to analyze the nature, characteristics, development and change of the object.
Quantization is described in mathematical language. It is a method of establishing a mathematical model based on statistical data and analyzing quantitative characteristics, quantitative relations and quantitative changes with the mathematical model.
Same:
They generally analyze and explain problems by comparison. It reflects the quantity, quality, benefit, consumption and development speed through the comparison of various indicators or the same indicator in different periods, thus providing conclusive information for identification and judgment.
Advantages and disadvantages:
Comparatively speaking, the quantitative analysis method is more scientific, but it requires profound mathematical knowledge, and the qualitative analysis method is rough, but it is more suitable when the data is insufficient or the analyst's mathematical foundation is weak. Qualitative and quantitative analysis methods are usually used in the analysis process.
(Method of combining qualitative analysis with quantitative analysis)
The relationship between qualitative analysis and quantitative analysis;
Qualitative analysis and quantitative analysis should be unified and complementary; Qualitative analysis is the basic premise of quantitative analysis, and quantitative analysis without qualitative analysis is blind and worthless; Quantitative analysis makes qualitative analysis more scientific and accurate, and can promote qualitative analysis to draw extensive and in-depth conclusions.
In fact, modern qualitative analysis methods also need to use mathematical tools to calculate, and quantitative analysis must be based on qualitative prediction. The two complement each other. Qualitative analysis is the basis of quantitative analysis, and quantitative analysis is the embodiment of qualitative analysis. Only flexible combination can achieve the best effect.
