What is normal IQ for an adult?

Answer 1

By definition, the normal IQ is 100. I.Q. stands for "Intelligence Quotient." So, the number is the result of a number divided into another.

Let's say you have a 10 year old boy. But, his brain is as mature, smart and developed as a kid two years older than he. His brain is as intelligent as a 12 year old's. His IQ would be 120. 12 (his brain's "age") divided by 10 (his actual age) equals 1.20.....120. Now, lets say we have a 12 year old boy, but his brain is under-developed. His brain's "age" is only that of a 10 year old. His IQ would be 10/12. That equals .83. His IQ would be 83.

Of course, this runs into problems as a person gets older. As you get into your 50's, 60's and older, you tend to lose brain cells, and lose intelligence. How should IQ be measured then? IQ is based on the theory that as you get older, you get smarter. But, after a certain age you do lose brain cells.

Another problem is what is "normal development," or "normal intelligence" for a certain age. That is a very subjective issue. It all depends on which psychiatrist you ask.

IQ is probably NOT the best way to measure a person's intelligence, but it probably is the best way we have so far.

Answer 2

The average IQ is 100, which means that more people have that as an IQ than have any other IQ score.

A person with an IQ of 90 is a little "slower" than average. People who have IQ's between 110 and 130 belong to a fairly large group and are "nicely above average".

In order to really understand one's abilities, however, it would be important to know how one scores on each of the different tests that tests different types of ability; because a person could have a score of 150 when it comes to one skill and 90 when it comes to another one.

Answer 3

by definition, the traditional IQ is one hundred. I.Q. stands for "Intelligence Quotient." So, the large form is the end results of a huge decision divided into yet another. enable's say you've a 10 year previous boy. yet, his mind is as mature, smart and developed as a baby 2 years older than he. His mind is as wise as a 12 year previous's. His IQ may be one hundred twenty. 12 (his mind's "age") divided by 10 (his truthfully age) equals a million.20.....one hundred twenty. Now, shall we are saying we've a 12 year previous boy, yet his mind is lower than-developed. His mind's "age" is largely that of a 10 year previous. His IQ might want to be 10/12. That equals .80 3. His IQ might want to be 80 3. for sure, this runs into issues as someone receives older. As you get into your 50's, 60's and older, you've a tendency to lose mind cells, and lose intelligence. How might want to IQ be measured then? IQ is depending on the concept as you become older, you get smarter. yet, after a particular age you do lose mind cells. yet another challenge is what's "accepted progression," or "accepted intelligence" for a particular age. it truly is a very subjective challenge. it easily relies upon on which psychiatrist you ask. IQ might want to not be a thanks to degree someone's' intelligence, inspite of the indisputable fact that it in all likelihood is the perfect way we've so some distance.

Answer 4

Normal is considered 90 -110 on most tests. Below 70 is mentally deficient (for lack of a better term) and 80-90 is below avergae (what used to be called a "slow learner"). 110-120 is above average and "genius" starts at 140.
