Before going fully into the meaning of the term statistical data, we are going to proceed to know the etymological origin of the two words that give it its shape:

-Data, first of all, comes from Latin. Exactly “datum”, which is synonymous with “data”.

-Statistics, secondly, it is a word that was developed by the German economist Achenwall who created it from the German “statistik”, which, in turn, derives from Latin. Specifically, the Latin term “statisticus”, which is the result of the sum of two differentiated parts: the noun “status”, which is synonymous with “state”, and the suffix “-icus”, which is used to indicate “relative to ”.

Statistical data is useful for making decisions.

The term fact refers to the information that provides access to precise and concrete knowledge. Statistical, for its part, is what is linked to statistics: the specialty of mathematics that uses figures to generate inferences or to quantitatively reflect a phenomenon.

What is statistical data

The statistical data, in this framework, are the values obtained by carrying out a statistical study. Its about observation product of that phenomenon to be analyzed.

Suppose a sports journalist wants to study the performance of a tennis player based on the results he achieved in the last year. Within that period, the player played fifteen matches, of which he won 5 and lost 10. The statistical data obtained from observing the matches are as follows: defeat – defeat – defeat – victory – defeat – victory – victory – defeat – defeat – defeat – defeat – defeat – victory – defeat – victory.

Statistical data processing allows information to be generated.

The organization and context

To be useful, statistical data must be organized and considered on the basis of a context. Returning to the previous example, said data will be valuable if it is known to which tennis player they belong and in what period or period they were obtained by the athlete.

It is important to note that the statistical data processing is what generates information. The data by itself, considered as something isolated, is of no interest.

Obtaining and processing statistical data are very important tasks for the decision making in various fields. A governmentFor example, you need reliable statistical data to decide your economic policy.

Other characteristics of statistical data

In addition to all the above, there are another series of aspects that we can highlight about the statistical data, such as the following:

-They have the peculiarity that at all times they are subject to an interpretation, which is the one carried out by the person who carries them out or who uses them. In the same way, also the reader of the same or the listener of the presentation of those will be able to make their own interpretation as well.

-They have the uniqueness that they are used on many occasions to persuade or convince. And it is more convincing to talk about 90% of the people, for example, than to say “many people”.

-Statistical data is essential that they are always accompanied by the so-called margin of error or sampling error that, always, it is recommended that it be as low as possible.
