Statistical indicators - a quality, as well as the quantitative characteristic of any property of any collection.Both these parties form the structure of the concept.Quality is determined by the sign, which is studied, it is possible to judge about the title figure.A quantitative aspect is displayed in numerical values.
system of statistical indicators includes a combination of several of these characteristics.It is used to examine and display the quality and quantity of processes and phenomena occurring in society.There is always taken into account the conditions of a particular place and time.
characteristics which give the statistics always generalizing.This is their main difference from the individual values of a trait.For example, a particular variation - the salary of an individual employee of the company, and the average salary of all employees of the same firm - this is a statistical measure.It can be obtained, unlike the first, only through simple or complex calculations.
Since the statistics reflect the different sides of the processes and phenomena occurring in the economy and in social life, they can be more.You can classify them on several grounds:
1. As population units, which can be as follows:
1) Summary.This is a general, abstract figures.They give the characteristics of the entire population as a whole and are divided in turn into:
- calculated.They are produced using special formulas.They need to solve certain problems of statistical analysis.
- Volume.They are obtained by summing the number of feature values of certain elements of the set.
2) Individual.They characterize only one unit together or a single object.This could be, for example, the number of employees in the company.
2. Classification of statistics on the functions they perform:
1) Forward.They show that what may be the state of the phenomenon that is studied in the future.
2) credentials.They show the state in which the phenomena are subjected to research are currently.
3) Plan.They focused on the fact that the tasks performed.
3. The form of expression:
1) Relative.In relation to these figures absolute secondary derivatives.They express that in which the relation between a quantitative characteristics are statistical aggregates.Calculated by dividing the relative indicators of absolute indicators.They can be named, and expressed in percentages or ratios.Relative indicators are divided into three subspecies:
- structure;
- plan;
- dynamics.
2) Absolute.It is the original form, which is expressed in statistics.These values give a description of the absolute size of the phenomena being studied.It is always the named number.Expressed in absolute figures in value units, labor and natural.
3) Average.This form of the most common indicators.It characterizes the level of typical events.This rate can be calculated by one or feature, or combination of the statistical unit.
4. At the time factor:
1) Torque.They give a response to the processes and phenomena that occur in the economy and in society at a certain date.
2) Interval.They give a response to the processes and phenomena that occur in the economy and in society for a certain time period (year or month, quarter, etc.).
To describe all indicators using symbols and images in the statistics made to use special drawings - graphics.
