what is the normal IQ for a 15 yr old?
549474
The "normal" IQ for anyone is 100. That means most everyone will fall within one standard deviation of 100 - IE: in the 90 - 110 range.\n\nYou can pretty safely assume that your IQ is somewhere in that range.\n\nMentally retarded is someone who has an IQ of 70 or below.\nGenius is someone who has an IQ of 140 or above.\n\nHope that helps!

The average for every age is 100.  Your IQ is your age divided by your intelligence age.  That should equal 1 for a normal person.  Then you multiply that number by 100.  So, 100 is normal and 150 or above is genius level.

It doesn't matter what grade you're in or how old you are. An IQ test does not determine your level of intelligence. It measures how easily you learn. Your IQ, if tested properly, should stay the same throughout your life. Oh, and a 126 is above average.

145+ is borderline genius and 160+ Is genius. Below 80 is considered socially retarded. You can do an online search for Intelligent Quotient ( IQ) and you can not only see different scores and their determining factors. but you can take several sample tests. I wouldnt take just one and live by that score as different tests are rated differently. I took 3 and then took the avereage of the scores to guestimate what my IQ is.

Well, according to Tickle.com, the average person taking their IQ test scored a 115.  The highest average was in DC, with 119, and the lowest was Mississippi, with 112. But, who really knows.  It's not like everyone in the countries take the stupid test.  I scored a 132, and guess where I live...Mississippi.  Go figure.

Actually, the intelligence quotient is defined as 100 times the Mental Age (MA) divided by the Chronological Age (CA).\n\nIQ = 100 MA/CA.\n\nThe 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.

Most IQ tests are normed for a definite population so that the average IQ will lie between 90 and 110 (with the mean 100) on the Stanford-Binet Intelligence Scale.\n\nHowever, an individual scoring at 100 within one population can score above or below that value within another population.\n\nFor example, the Japanese are supposed to have the highest average IQ in the world (115 St-Bin). I.e. compared to a calculated mean for the world. Still they have only an average of 100 within their own population.

tell him no. Geez. 15 is too young to have a brain apparently.

If a 68-year-old person has an IQ of 122, it means that his intelligence is above average. This is because the average score for a 68-year-old person is 100.

It depends what test and what kind of scores they generate.\n\nSome publishers like using percentiles, T-scores, or the most common, Standard Scores. The highest Standard Scores on a "real" IQ test usually do not go higher than 145.\n\nHere are the following standard score descriptions.\n\nlower than 69 Mentally retarded range\n79 to 70 borderline\n80 to 89 below average\n90 to 109 is average\n110 to 119 High Average\n120 to 129 Superior\n130+ Gifted range

Well, by IQ standards, that is considered above average.  The IQ test is not a very good test.  It does not truly test your ability to think or to reason.  Just like the SAT's, your IQ can improve everytime you take it.  Try it again and see what you get.  I did that, and the first time I got a 137 and the second time I got a 143.  I have also taken an IQ test administered by a psychologist and I scored 140.  It was much longer than the online version.  It took about 2 hours.  I believe that the scoring changes depending on the version.  A 135 is very good though, just don't put too much stock in it.  By the way, the high school that I went to required an IQ of 131 to enter the gifted program.

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. \n\nHalf of the population have IQ’s of between 90 and 110, while 25% have higher IQ’s and 25% have lower IQ’s: \n\nDescriptive Classifications of Intelligence Quotients\n \n \n 130+\n Very superior\n 2.2%\n \n120-129\n Superior\n 6.7%\n \n110-119\n High average\n 16.1%\n \n90-109\n Average\n 50%\n \n80-89\n Low average\n 16.1%\n \n70-79\n Borderline\n 6.7%\n \nBelow 70\n Extremely low\n 2.2%

In theory there should be no difference in IQ from age to age, because what theoretically happens is you're comparing your mental age to your physical age--basically you're seeing if you know more or less than other people your age.  If you were absolutely average for people your age, your IQ would be 100.  However anything in the range from 85 to 115 would be very normal.  Realize also that the short IQ tests often found online are notoriously unreliable and that IQ in general really doesn't tell how smart you are; it tells how well you did at taking a single test.
