The Discipline "higher mathematics" some causes rejection, since indeed not everyone can understand it. But those who were lucky enough to study this subject and solve problems using various equations and coefficients, can boast of almost complete it osvedomlennosti. In psychological science there is not only a humanitarian focus, but also certain formulas and methods for mathematical verification, put forward the research hypotheses. For this purpose different factors.
This is a common measurement for determining the closeness of the connection between any two signs. The coefficient is also called the nonparametric method. It shows statistics of when. That is, we know, for example, that child aggression and irritability, are interrelated, and the correlation coefficient of rank Spearman correlation shows statistical mathematical relationship of these two characteristics.
Of Course, that all mathematical definitions or values, there are formulas by which they are calculated. It has a Spearman correlation coefficient. The formula for he as follows:
At first glance, the formula is not entirely clear, but if you look, everything is very easy to calculate:

To apply rank coefficient requires that the quantitative characteristic data were ranked, that is, they were assigned a certain number depending on where the sign is located, and from its meaning. It is proven that the two rows of signs, expressed in numerical form, somewhat parallel to each other. The Spearman rank correlation coefficient determines the degree of parallelism, the closeness of the connection characteristics.
For mathematical operations for the calculation and determination of connection characteristics using the specified coefficient, you need to perform some actions:
The main properties of Spearman's coefficient include the following:
To check the communication characteristics between a need to perform certain actions:
The first science, where he actively used this ratio, was psychology. Because it is a science, not based on numbers, but the proof of any important hypotheses concerning the development of relations, traits of people, knowledge students, need statistical confirmation of the conclusions. It is also used in the economy, particularly when foreign exchange turnover. Are signs without statistics. Very convenient Spearman rank correlation coefficient in this application that the evaluation is carried out independentlyfrom the distribution of the variables as they are replaced by the rank number. Actively used the Spearman coefficient of banking. Sociology, political science, demography and other Sciences also use it in their research. Results are obtained quickly and accurately.
Conveniently and quickly used the Spearman correlation coefficient in Excel. There are special functions which help to quickly obtain the necessary values.
Besides, what have we learned about correlation coefficient, there are various correlation coefficients that measure, evaluate qualitative characteristics, the relationship between quantitative traits, the closeness of the connection between them, represented in the rank scale. It is such factors as viscerally, rank-viscerally, contingencies, associations, and so on. The Spearman coefficient shows very accurately the closeness of the connection, in contrast to all other methods of mathematical definitions.
