Brief introduction of rectification:

Tidy up (put things in order) Everything must be put in the right place at the scene and can be used immediately when needed. Each project should have a specific location and must be placed in that location. Whether the markings on the ground are correctly marked, whether there are no obstacles in the passage, and if the rectification is done well, it is easy to see that everything is positioned.

Constant volume:

Constant volume refers to the process of injecting water into the volumetric flask with a rubber dropper at the water distance from the calibration line 1 ~ 2cm, and the line of sight is flush with the lowest concave liquid level, so as to make it reach the calibration line.

Quantitative:

Quantification refers to definite quantity, specified quantity and limited quantity. Because it has a certain limit, it is exclusive, that is, this quantity rather than that quantity. "Quantization is a quantity with specified or general boundaries", "Quantity is quantification, or, whether it is continuous or discrete, it has boundaries".

Brief introduction of quantitative research and quantitative analysis;

1, Introduction to Quantitative Research:

Analyze and study things from the quantitative aspect, and use mathematical methods to study and examine the methods of mutual connection and interaction between things. Everything is the unity of quality and quantity. Qualitative research without quantitative research can only have a general understanding of things, which is neither accurate nor comprehensive, and may even be wrong. Because without quantity, there is no quality.

Quantitative change to a certain extent will lead to qualitative change, so it is very necessary to analyze the basic quantity of things Quantitative research is to grasp the stipulation of things by analyzing the stipulation of things. Social statistics is the most commonly used quantitative research method in sociological research.

2. Introduction to quantitative analysis:

Refers to the use of mathematical tools to analyze the quantity of things. There are a lot of data reflecting the quantitative relationship and complex structure of cultural phenomena in social life. These materials are indispensable information resources for cultural studies. Only by taking data as the research basis and making cultural research develop from qualitative research to quantitative research can people have a deeper and more accurate understanding of cultural phenomena.

The quantitative analysis method commonly used in cultural anthropology is social statistics.
