## Definition of coefficient

### 1 Meaning of coefficient

Agreement and according to the context in which it is applied, a coefficient can refer to something together with something else causes a certain effect.
Meanwhile, in the field of physics, a coefficient will be the numerical expression, which, through a formula, will determine the characteristics or properties of a body, for example, expansion coefficient, in drag, attraction, of broadcasting, among others.
On the other hand and in a field different, as it is that of mathematics, is designated with the term coefficient to the multiplicative factor belonging to certain object such as a variable, unit vector, function base, being the most important the binomial coefficient, which is the one that will indicate the number of forms that can extract subsets, starting from a given set.
And finally one of the most famous and popular in the world, coefficients but it is more, it is IQ, which refers to the number that results from the practice of a standardized test that measures cognitive abilities of an individual in relation to the age group to which it belongs.
Its abbreviation is CI and is considered that 100 is the average in an age group, if passed this brand, then we will be facing a person to possess a higher CI normal, for which that person has a higher intelligence than the rest of their peers.

### 2. Definition of coefficient

Coefficient or IQ is a compendium of features of human beings, summarized in a result estimated in a numerical amount, commonly known by its acronym in German "IQ" (Intelligence Quotient). The coefficient is calculated by means of a series of evaluations which allow to determine what the scope of the intelligence of the person, so that the evaluation indicates which is the response capacity in areas such as general knowledge, specific subjects as history, math, geography, science in general how physics and chemistry, among others. The IQ of people is also measured through tasks and resolutions that are assessed to give to these, this is usually done in schools, is measured periodically and remains a statistic to determine what has been the intellectual advancement of the person.
Measurement of the coefficient of the people has helped the educational systems of the country generate categories that are set to students of low, medium, or outstanding academic attitude, this has created a series of definitions depending on the availability of lifestyles, particularly in the United States. IQ in education is an essential tool when it comes to distribute functions for society in general, in this order of ideas, it is known that there are categories A, B, and C, where A represents the outstanding, people with highly developed intellectual coefficient, allowing them to be included in projects and careers of virtuous reputation. In category B enter people with a median IQ, generally stand always in any matter or sport, but they don't get A rating because of difficulties in some primordial matter. Finally the C category includes those subjects that do not exceed a basic expectation, which are not included or in the B or, in general, are people with an inefficient education, with economic constraints, which do not have the opportunity to be inserted in societies with a higher category.
The concept of coefficient opens the doors to give answers generated around the word intelligence, which is nothing more than the capacity acquired by the process of nutrition that the intellectual coefficient is measured.

### 3 Concept of coefficient

Also known as IQ, IQ is a number that results from a standardized assessment that allows to measure the cognitive abilities of a person in relation to his age group. This result is abbreviated as CI or IQ, the English concept of intelligence quotient.
As standard, is considered medium in an age group IQ is 100. This means that a person with a CI of 110 is above the average among people of his age. As normal is the standard deviation of the results of 15 or 16 points, since the tests are designed so that the distribution of the results is approximately a normal distribution. It is considered how gifted to those who are above 98% of the people.
It would much previously how to define intelligence. Intelligence there are many definitions for the term. Which established the American Psychological Association says consisting of skill through which individuals are capable of understanding complex things and to confront and resolve certain complications through reasoning; According to each person's ability is said that it is more or less intelligent than other.
It should be noted that according to this definition the intellectual abilities of each individual vary at the time that make problems to those who must face.
Mainstream Science on Intelligence suggested a second definition, corroborated by more than 50 researchers. It is postulated that intelligence includes the skills of reasoning, solve problems, think abstractly, planning.
Intelligence is not the faculty to learn from books, only, but also the skill to resolve conflicts and know what what to do at each moment.
Several types of tests should be performed to establish the intellectual faculties of a person. These tests include problems with words or numbers, shapes and designs, in order to be able to define the individual capacity of the individual CI.
On the other hand, it is necessary to define emotional intelligence to understand the differences between CI of different individuals. EI includes skills such as perception of feelings (own and the emotions of the environment), use of the emociones(dominar los sentimientos con el fin de facilitar una actividad cognitiva), the emociones(comprender el lenguaje de los sentimientos y reconocer cómo evolucionan en el tiempo) understanding and control of emotions (ability to manage own feelings depending on the needsto achieve the goals that have been proposed).

#### Studies on the CI

According to some studies carried out in the University College of London, to find out if the CI remains indelible to the passage of time or if you change, it has been discovered that the IQ of a person changes significantly as it grows; in some cases its value increases and others decreases.
He discovered also that changes in the language-related CI, associates are with variations in a region of the brain, more precisely in the left motor cortex. Furthermore, in relation to the non-verbal tests, it is known that it may be due to an increase in gray matter residing in the former cerebellum (which controls the motor and sensitive part of the body).
Is also known that there are differences in IQ between men and women, this does not mean clearly that one is more intelligent than another, but that they have different cognitive abilities; the same occurs in persons belonging to some and other cultures, because beyond social learning there is a certain predisposition to develop a specific form of CI.
History, on the other hand, shows that the scores in one assessment given and in a particular population has tended to climb. Therefore, the test that measured IQ must be updated periodically to keep the previous standards.
This phenomenon is known as the Flynn effect, thanks to the studies of James Flynn. This New Zealand specialist in political matters was who warned that IQ scores climbed in the world an average of three points per decade. Among the explanations given by the specialists, are a higher quality education, healthy nutrition and a greater preponderance of families with a reduced number of members.
