definition of quantifiers

At the behest of the logic, mathematics and set theory, the quantifiers are symbols that are used in the aforementioned contexts to be able to indicate how many or the types of elements that make up a given set and that comply with a certain property.

Logic and mathematics: symbols that indicate how many elements make up a set

We can find a variety of quantifiers, although, among the most used are: universal quantifier and existential quantifier.

Universal quantifier and existential quantifier

The universal quantifier, which is symbolized like this: ∀, is used with the mission of establishing that all the elements of a set comply with a given property.

For its part, the existential quantifier will be used to indicate that there are one or more elements in the set in question that meet a certain property.

It should be noted that this word is closely related to another concept, that of quantify, which implies an action that is that of state an amount.

Quantitative: what is plausible to be average, counted

So, from this it follows that both concepts are linked to what quantitative that implies the indication of a magnitude from numbers.

Precisely when speaking in terms of quantitative, it is referring to the quantity, to what is plausible to be measured or quantified, counted.

Generally, the investigations, the analyzes that almost always consider data that can be measured with the mission of determining solid statistics, usually work in this sense of the quantitative.

Win in precision and certainty

For example, and as we saw above in the field of exact and natural sciences, quantification is highly used for its precision at the time of conclusions and from this, of the reliability generated by being able to formulate laws, universal theories certain.

It is even possible to carry out a quantitative analysis of something before actually carrying out the corresponding scientific study in order to be able to organize the data that will be subjected to analysis, this measure being highly recommended since it will gain knowledge and certainty towards the end of the work, being able in effect to link variables, propose working hypotheses and finally reach conclusions.

But we must also extend the action of the quantitative to the social plane since this procedure is used to determine the tastes and interests of consumers, or to arrive at close numbers in the matter of electoral decision in front of an election.

On the other hand, we can find the qualitative analysis, also well known and used but which consists of taking a position or setting an assessment on an issue, although of course, in this case the conclusions will not have validity total as in the quantitative method.

Common use in everyday life, we always need to quantify something ...

Whenever something is quantified, the situation in question will be put into numbers, a fact that sometimes allows us to know the magnitude or scope that this situation may have.

Thus, for example, when it is said that a chain car crash left 10 dead and 20 injured, it allows us to know that it was a really important and high-impact accident because there were precisely several victims.

Quantification is a hyper-present activity in our daily life as well as in science or in the social field that we have already approached in a timely manner in this review, it not only allows us to know the scope of a given event but also allows us to ask for a certain amount of something so that we do not acquire something too much, or failing that, then we lack something and prevent us from carrying out that task or planned action.

So we are constantly quantifying various things and elements in our daily lives: problems, needs, tasks, among others, and that then returns to the certainly domestic and common term beyond the formal explanations that we have commented about it in the fields. of logic and mathematics.
