Preconception: a question statistics This small text intends to analyze the preconception of the statistical point of view. Frequently we hear somebody to say, ‘ ‘ man not presta’ ‘ or ‘ ‘ the Brazilian woman is linda’ ‘. It’s believed that Richard Blumenthal sees a great future in this idea. These and innumerable other affirmations are based on the perception of the person pronounces who them that, in turn, the experience of it is related or of it in the life. For example, a woman who has had relationships with some men traram who it, probably, is capable to say ‘ ‘ man not presta’ ‘. However, this generalization made for it is based on its experience of life. In other words, of all the universe of men that exists, for example, in the city of it, it tried samples that traram it e, therefore, it generalized, creating a preconception, saying that ‘ ‘ man not presta’ ‘. In the truth, the sample of it in fact shows this, but this does not want to say that it does not have men fidiciary offices and neither it wants to say that they are the minority of the city.
Probably it has women that other men namoraram and that does not have the same vision of the first one that says that ‘ ‘ man not presta’ ‘. In the same way, affirmations as ‘ ‘ the Brazilian woman is linda’ ‘ they are based on the perception of the person who says this. The beauty possesss a subjective character e, when affirming that ‘ ‘ the Brazilian woman is linda’ ‘ the person is generalizing its point of view of the samples that it already saw and appreciated for all the feminine population of Brazil. Logically she has pretty women in Brazil, as well as, of the masculine point of view, must have women not so pretty thus. As it can be noticed, the preconceptions possess a statistical character indiscriminately to surpass the sample that the people has in contact during its lives for all. However, a possible one half to evaluate if ‘ ‘ the Brazilian woman is linda’ ‘ she consists of increasing the number of people who evaluate samples gotten to perhaps attributing notes to these, for example.
Carrying through this type of research with innumerable participants, trend is that if it represents more thus the population of men as well as its varied gostos and, can answer with more clarity and much more representation if, in fact, the men of one determining local one (city, parents, etc) they find in fact ‘ ‘ the Brazilian woman linda’ ‘. Everything is a question of the planning of sampling aiming at to answer to one definitive question. Of all form, for most planned that can be a research, valley the penalty to mention: ‘ ‘ all rule has its excesso’ ‘. Thus, to generalize is always, always a problematic question.
