What Are the Different Types of Quantitative Analysis Tools?

Quantitative analysis method (quantitative analysis method) is a method to analyze the quantitative characteristics of social phenomena, quantitative relationships and quantitative changes. In business management, the quantitative analysis method uses the company's financial statements as the main data source, and processes and arranges according to a certain mathematical method to obtain the corporate credit results. Quantitative analysis is the analysis of quantifiable data of a company by an investment analyst using a mathematical module, and the company's operation is evaluated and investment judgments are made through analysis. The objects of quantitative analysis are mainly financial statements, such as the balance sheet, profit and loss account, retained income statement, etc. Its function is to reveal and describe the interaction and development trends of social phenomena.

The size of the numerical value used in the order scale corresponds to the specific order of the research objects. For example, "5,4,3,2,1" or "3,2.5,2,1.5,1" or "3, 2.5, 2, 1.5, 1" for the upper, middle, upper, middle, lower and lower tiers of the social class belong to this one type. It is just that the difference between the 5 representing the upper and upper layers and the 4 representing the upper and middle layers, and the difference between the 4 representing the upper and middle layers and the 3 representing the middle layers are not necessarily equal. 5, 4, 3, etc. are arbitrarily added symbols, if it is written as 100, 50, 10, it is not a problem.

The numerical value used for the pitch scale not only indicates the amount of the measurement object, but also the degree of their size, that is, the size of the interval. However, the origin in this scale can be set arbitrarily, but it does not mean that the amount of the thing is "none". For example, O ° C is 273 ° K absolute and 32 ° F.

The values of the nominal scale and the ordinal scale cannot be added, subtracted, multiplied, and divided, but the values of the interval scale can be added and subtracted. However, since the origin is arbitrarily set, multiplication and division cannot be performed. For example, the difference between 5 ° C and 10 ° C can be said to be the same as the difference between 15 ° C and 20 ° C, both of which are 5 ° C. But it cannot be said that 20 ° C is 4 times higher than 5 ° C.

The meaning of the scale is absolute, that is, it has an origin of 0 meaning "nothing". Length, weight, time, etc. are all measured on a scale. The differences and ratios of the measured values on the scale are comparable. For example: the difference between 5 minutes and 10 minutes and the difference between 10 minutes and 15 minutes are 5 minutes, and 10 minutes is 5 times 2 minutes. The scale can be added, subtracted, multiplied and divided.
