What is statistical data?

What Does statistical data Mean

Before entering 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 shape:

-Data, in the first place, 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 from 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 ”.

The term data refers to the information that provides access to precise and concrete knowledge. Statistical , on the other hand, is that linked to statistics : the specialty of mathematics that appeals to figures to generate inferences or to quantitatively reflect a phenomenon.

The statistical data in this context are the values which are obtained carrying out a study of statistical type. It is the product of the observation of the 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. In that period, the player played 15 games , of which he won 5 and lost 10 . The statistical data obtained from the observation of the matches are the following: defeat - defeat - defeat - victory - defeat - victory - victory - defeat - defeat - defeat - defeat - defeat - victory - defeat - victory.
To be useful, statistical data must be organized and viewed in 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 bear in mind that the processing of statistical data 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 decision-making in various fields. A government , for example, needs to have reliable statistical data to decide its economic policy.
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 particularity that at all times they are subject to an interpretation, which is the one made by the person who takes them to out or who employs 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”.

-The 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.
