Importance of Statistical Data

The importance of statistical data is based on the fact that they serve to assess the future trend of a given phenomenon.. Indeed, after careful analysis, statistical data can reveal to some extent what to expect in the future in some area of ​​human activity. That is why the way in which such data is collected is essential, seeking at all times to ensure that they are representative of a larger universe. Some Applications of this statistical procedure based on data collected may refer to the scope of the policy, finance, marketing, etc.

The evaluation of the data in statistics is based on an inductive process. This means that from a small number of particular data, an attempt is made to draw a general conclusion. From the point of view Logically, there are many objections to this process; in fact, the fact that a determined number of cases shows a regularity does not mean that it can be transferred categorically to a greater number of cases. That is why these types of evaluations are always subject to error. However, it is surprising to observe the degree of efficiency that has been achieved in this type of considerations. It is far from being a coincidence that they are used to study the most diverse subjects.

An example of the use of statistical data the field of politics can offer it. For example, when it is necessary to carry out a survey of the intention to vote for a certain candidate, surveys are usually taken in different social strata and in different regions of the country. This fact means that the sample lacks some deviation and that it is random. When the data is available, it is established what type of percentage would vote for said candidate based on the total number of people interviewed; This percentage would be transferable to the whole of the population of the country in question. Thus, if ten percent of a sample of one hundred thousand cases would take a certain action, one tends to conclude that the same percentage would take it considering one million cases.

As we see, the process has certain certain objections. They are known and accepted, therefore evaluating a margin of error in the established conclusions. However, this type of evaluation of the statistical data It allows generating a sufficiently clear picture of a future circumstance, a fact that as we know is something useful to specify.
