Qualitative research is a social science research method formed under the influence of anti-positivism theory. It tends to use interview, observation and literature to collect data, and conduct research on the basis of subjective understanding and qualitative analysis. Qualitative research emphasizes that human behavior is a meaningful action, and human's construction of social reality is completed on the basis of the meaning given to social objects by the subject and others who participate in the interaction, and also produces rules or knowledge with common knowledge in daily life. It is difficult to quantitatively study these rules or knowledge and their production process. Qualitative analysis is the qualitative analysis of the research object. Specifically, it is to use the methods of induction and deduction, analysis, synthesis and abstract generalization to process the obtained materials, so that we can get rid of the rough and get the essence, discard the false and keep the true, from here to there, from the outside to the inside, realize the essence of things and reveal the internal laws, from qualitative to quantitative.
Question 2: What does qualitative analysis mean? qualitative analysis
It is a qualitative analysis of the research object.
Qualitative analysis: dry analysis and wet analysis, the former sample does not need to be made into solution, such as molten bead analysis, flame color analysis, atomic emission spectrometry, X-ray fluorescence spectrometry and so on.
The main task of qualitative analysis is to determine the composition of substances (compounds). Only when the composition of the substance is determined can the appropriate analytical method be selected for quantitative analysis. If it is only to detect the presence of certain ions or elements, it is for separate analysis. If you need to remove other interfering ions and elements through a series of reactions or know what other ions and elements exist, it is systematic analysis.
Question 3: What does qualitative analysis mean? The word you mentioned belongs to FRM vocabulary. Mastering FRM vocabulary can make you feel at home in FRM. The translation and meaning of this word are as follows: according to non-financial information, such as management quality, industry periodicity, R&D intensity and labor relations, the securities analysis method is evaluated by subjective judgment.
Question 4: What is qualitative analysis? What is quantitative analysis? ) qualitative analysis qualitative analysis is a qualitative analysis of the research object. Specifically, the method of induction and deduction, analysis, synthesis and abstract generalization is used to process the obtained materials, so as to get rid of the rough, get rid of the false and keep the true, understand the essence of things and reveal their internal laws. Qualitative analysis is mainly to solve the problem of whether the research object exists or not. Qualitative research is divided into three processes: 1, analysis and synthesis 2, comparison 3, abstract and generalized quantitative analysis quantitative analysis: the analysis of quantitative characteristics, quantitative relations and quantitative changes of social phenomena. Its function is to reveal and describe the interaction and development trend of social phenomena. Qualitative analysis-quantitative description of written language-qualitative analysis and quantitative analysis of mathematical language are two analytical methods used by people when they know things [1]. As early as in ancient Greece, the concept of qualitative analysis was very mature. At that time, a group of famous scholars made a physical explanation of the natural world they studied in their own research. For example, Aristotle studied many natural phenomena, but in his thick works, he could not find a mathematical formula. He described the essence of every phenomenon and defined the essence of every natural theorem he discovered. Although this kind of knowledge is indispensable for us to understand the sensory world, it lacks the basis for in-depth thinking, because extending from one nature of things to another often exceeds human cognitive ability. Quantitative analysis, as the basic thinking mode of analyzing problems, began with Galileo. As the founder of modern science, Galileo applied quantitative analysis to his own research for the first time. From motivation to astronomy, Galileo abandoned the analysis that people only made subjective guesses about the cause and result of things before, and replaced it with experiments, mathematical symbols and formulas. It can be said that Galileo's decision to pursue description is the most profound and effective change about scientific methodology. Its importance lies in putting science under the protection of science. " And mathematics is a science about quantity. It can be said that a science can only be called science if it successfully uses mathematics. From the perspective of rational development, Galileo's scientific method of substituting quantity for quality makes the object of human cognition clear from vagueness and concrete from abstraction, which makes human rationality add quantitative characteristics on the basis of quality. Because of this substitution, those concepts unrelated to quantity, such as the nature of essential origin, are replaced by brand-new concepts such as space, time, weight, speed, acceleration, inertia force and energy in a certain field and range. Therefore, quantitative analysis, as an ancient way of thinking that has not been accurately positioned, has obvious advantages over qualitative analysis. It defines things within the range that human beings can understand, from quantity to quality. 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 it more scientific and accurate, and qualitative analysis can draw extensive and in-depth conclusions. Quantitative analysis is a method to establish a mathematical model based on statistical data, and use the mathematical model to calculate the indexes and their values of the analyzed object. Qualitative analysis is a method that mainly relies on the intuition and experience of the analyst, the past and present continuity of the analysis object and the latest information to judge the nature, characteristics and development and change law of the analysis object. Comparatively speaking, the former method is more scientific, but it requires advanced mathematical knowledge. Although the latter method is rough, it is more suitable for ordinary investors and economic workers when the data is insufficient or the mathematical foundation of analysts is weak. However, it must be pointed out that although the two analytical methods have high or low requirements for mathematical knowledge, qualitative analysis and quantitative analysis cannot be completely separated. 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. Different analysis methods have their own characteristics and performances, but they all have one thing in common, that is, they generally analyze and explain problems through comparison. It reflects the quantity, quality, efficiency and consumption through the comparison of various indicators or the comparison of the same indicator in different periods. & gt

Question 6: What do quantitative analysis and qualitative analysis mean? For example.
For example, in the field of chemistry,
Qualitative analysis is to determine what elements a substance consists of;
Quantitative analysis is to find the chemical formula of a substance (calculate the amount of each element).
Question 7: What are qualitative analysis and quantitative analysis? Quantitative research: Like natural science, it is a research process of establishing research hypotheses, collecting accurate data, and then conducting statistical analysis and testing through statistical investigation or experiment. Quantitative analysis, as an ancient way of thinking that has not been accurately positioned, has obvious advantages over qualitative analysis. It defines things within the range that human beings can understand, from quantitative change to qualitative change.

Question 10: What does qualitative analysis mean? Qualitative analysis refers to the qualitative analysis of things. In order to grasp the essence of things in various sports research phenomena, we should take dialectical materialism and historical materialism as practical materials, and then comprehensively analyze these materials with correct views to find out the regularity of reappearance from the phenomena. That is, the essence. Only in this way can we describe a thing correctly and reveal the relationship between things. This analysis has certain reference value and evaluation for people to identify and judge the attributes of things. But we can only distinguish the conceptual standards such as height, length and size.
