The law of large numbers

Interacting daily in work or study with numbers and numbers, many of us do not even suspect that there is a very interesting law of large numbers, applied, for example, in statistics, economics and even psycho-pedagogical research.

In addition to the definition of the law of large numbers considered in the theory of probability considered above, we can also give its economic interpretation. In this case, it is the principle that the frequency of financial losses of a particular species can be predicted with a high degree of certainty when a high level of loss of such species is observed at all.

The law of large numbers expresses the most general laws of random and necessary. When random deviations "extinguish" each other, the average indicators, determined for the same structure, take the form of typical ones. They reflect the actions of significant and permanent facts in specific conditions of time and place.

The importance of the fact that the law of large numbers works, it is difficult to overestimate for any field of scientific knowledge, and especially for scientific developments in the field of statistical theory and statistical methods of knowledge. The effect of the law also has great significance for the objects under study with their mass regularities. On the law of large numbers and the principle of mathematical statistics, practically all methods of statistical observation are based.
