The concept of average is linked to the arithmetic average, which consists of the result obtained when generating a division with the summation of various quantities by the digit that represents them in total. Of course, this notion is also used to name the point at which something can be divided in half or almost in the middle and to refer to middle ground of a thing or situation.

The average, therefore, is a finite number that can be obtained from the sum of different values ​​divided by the number of addends. For example: if at a dinner, eight people drink five liters of wine, it can be said that the diners have drunk an average of 0.625 liters of wine per person.

The average is often very useful in statistics.

When working with averages, it is common for other concepts to emerge at the same time that are equally significant to analyze the field or sector where they are being carried out. Thus, we often speak of what is known as the median. This is neither more nor less than the term that is used to define the value that is in the right half between the maximum and minimum values ​​of the data with which you are working.

The second concept that is used when dealing with numbers and data in this sense is the fashionable one. This is used to refer to the data that is repeated more frequently among all those.

## Average and reality

The result of the average calculation, of course, does not always match reality: that’s why we speak of an average. Suppose that, in a neighborhood with a hundred houses, two hundred dogs live. The average indicates that they inhabit two dogs per house. In reality, however, some houses have three or more dogs, while others have no dogs.

To calculate an average, a calculator or computer program can be used.

This shows that an average is sensitive to values extremes. Very high values ​​tend to increase the average, while very low values ​​decrease it. In this way, the average may cease to be representative because it moves away from the mean of the population.

Take the case of a town of 100 inhabitants. There, five of the residents earn \$ 100,000 per month, while the other 95 residents barely receive \$ 1,000 per month. The average will indicate that said town has income of \$ 5,950 per capita, something quite far from reality.

## A Spanish institution

In addition to all the above, we can determine that average is also the name of an important institution in the province of Badajoz, in Spain. Specifically under this term, which acts as a name, is the Environmental Management Consortium of the aforementioned provincial council.

This body is, among other functions, in charge of carrying out the comprehensive management of the various local environmental services. In this way, it undertakes, for example, what is the control and development of both activities related to the supply of water as well as urban waste.

With this, what is achieved is that the municipalities that make up the province of Badajoz can make use of all these services in a fast, simple and favorable way.
