An intelligence quotient or IQ is a score derived from a set of standardized tests of intelligence. Intelligence tests come in many forms, and some tests use a single type of item or question. Most tests yield both an overall score and individual subtests scores. Regardless of design, all IQ tests measure the same general intelligence. Component tests are generally designed and chosen because they are found to be predictable of later intellectual development, such as educational achievement. IQ also correlates with job performance, socioeconomic advancement, and "social pathologies". Recent work has demonstrated links between IQ and health, longevity, and functional literacy. However, IQ tests do not measure all meanings of "intelligence", such as creativity. IQ scores are relative (like placement in a race), not absolute (like the measurement of a ruler).
For people living in the prevailing conditions of the developed world, IQ is highly heritable, and by adulthood the influence of family environment on IQ is undetectable. That is, significant variation in IQ between adults can be attributed to genetic variation, with the remaining variation attributable to environmental sources that are not shared within families. In the United States, marked variation in IQ occurs within families, with siblings differing on average by 12 points.
The average IQ scores for many populations were rising during the 20th century: a phenomenon called the Flynn effect. It is not known whether these changes in scores reflect real changes in intellectual abilities. On average, IQ scores are stable over a person's lifetime, but some individuals undergo large changes. For example, scores can be affected by the presence of learning disabilities.

IQ, "Intelligence Quotient" is defined as 100 times the Mental Age (MA) divided by the Chronological Age (CA).
IQ = 100 MA/CA.
The average IQ of the population as a whole is, by definition, 100. IQs range from 0 to above 200, and among children, to above 250. However, about 50% of the population have IQs between 89 and 111, and about 80% of the population have IQs ranging between 80 and 120, with 10% lying below 80, and 10% falling above 120.

IQ stands for intelligence quotient. Supposedly, it is a score that tells one how “bright” a person is compared to other people. The average IQ is by definition 100; scores above 100 indicate a higher than average IQ and scores below 100 indicate a lower that average IQ. Theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50 or above 150.

There's no maximum: it's based on 100 being "normal". A quotient, as you know, is the result of dividing one quantity by another: in this case, the numbers are the person's mental age and his actual age, and the result is multiplied by 100, so if your mental and physical ages are the same, your IQ will always be 100.
This metric is only really of value in assessing children: clearly the idea of a "mental age" of 57 is nonsensical.

Why have you ever printed this two times? immediately after one yet another, it is purely stupid, because you should a minimum of wait, or placed up it on a a range of of board! To be straightforward IQ, i imagine is over -rated - I dont understand mine yet I dont imagine it truly concerns once you're brighter than your dad or no longer. it type of feels a buit shallow, i must be extra afflicted about being a staggering man or woman, and also you're oviously no longer stupid if that's your IQ, so why do you care, see you later as you're sensible sufficient to do o.k. in existence (which will I upload you dont must have a severe IQ to do!) does it truly count number once you're brighter or no longer than your dad! also asking if you're a genius is undeniable huge - headed!

IQ is not out of anything. It is a ratio (I don't recall the exact composition) 100 is average, below 70 is retarded, and above 130 is genius.

I.Q. is Intelligence Quotient, the average I.Q. is set a a nominal 100 points, if your I.Q. is above 140 points you are regarded as gifted. The highest that I know of is a lady from London who has an I.Q. of 200+ and if your I.Q. is less than 60 then you are regarded as special.

Out of a perfect score. This depends on what test your taking. As a rule anything over 140 is great. Anything over 200 is likely a mistake. Anything under 70 and your starting to be retarded.
