Dynamics in essence is an indicator of the movement of process in a positive or negative side. It fixes development of an event, process, the phenomenon, etc. Therefore for calculation of dynamics of any process it is necessary to arm with its key indicators. For example, to make quantitative assessment of dynamics of the social and economic phenomena take the following statistics: gain, growth rate, rate of building, etc. As you could notice, all these indicators reflect in themselves the movement. It is put in determination of dynamics.
Instruction
1. Dynamics includes several levels, it is not so linear process. Therefore the method of comparison of its levels is the cornerstone of calculation of dynamics. Comparison it can be constant and temporary, during the chosen period.
2. So, to calculate dynamics, it is necessary to calculate an indicator of each of its sostavlyayushchikhabsolyutny gain. It is a difference in terms of basic data. That is basic gain and the constant level of gain at this stage. This indicator can be and negative.
3. Growth rate. It represents a ratio of two levels of a row and is expressed most often as a percentage or as coefficient. Correlate the received indicator to 1. If the growth rate turned out more than 1, then it means increase in level in comparison with basic. If the growth rate is equal 1, then any changes. And if the growth rate turned out less than 1, then decrease in level in relation to a basic indicator. Remember: the growth rate always has the positive sign.
4. Rate of building. The difference between a condition of process at the initial stage of the chosen period and on final. Is expressed as a percentage. A problem of this indicator is definition of the direction of the movement of the studied process and speed. That is what you have: decline or, on the contrary, rise and with what percentage separation. Such calculations are applicable almost in any sphere of activity and depend on degree of variability of the phenomenon.
