what is the maximum level for one's IQ?

IQ scores are expressed as a number normalized so that the average IQ in an age group is 100. In other words, an individual scoring 115 is above average when compared to people in the same age group. It is common practice to standardize so that the standard deviation (σ) of scores is 15, although some IQ tests use difference scales (for example, the Stanford Binet IQ test uses a standard deviation of 16, and the Cattell IIIB test uses a standard deviation of 24). Tests are designed so that the distribution of IQ scores is Gaussian; that is, it follows a bell curve. A difference has been documented between the IQ score distributions of left-handed and right-handed test subjects; the distribution in left-handed people tends to cluster at the two extremes of the IQ scale.\n\n(The following numbers apply to IQ scales standard deviation σ = 15.) Roughly 68% of the population has an IQ between 85 and 115. The "normal" range, or range between −2 and +2 standard deviations from the mean, is between 70 and 130, and contains about 95% of the population. An accurate score below 70 may indicate mental retardation, and a score above 130 may indicate intellectual giftedness. Retardation may result from normal variation or from a genetic or developmental malady; analogously, some otherwise normal people are very short, and others have dwarfism. Giftedness appears to be normal variation; autistic savants have often astonishing cognitive powers but below-average IQ's.\n\nIt has been observed that scores outside the range 55 to 145 must be cautiously interpreted because there are smaller numbers of respondents with which to make comparisons in those ranges. Moreover, at such extreme values, the normal distribution is a less accurate estimate of the true IQ distribution.\n\nIn actuality there is a higher percentage of the population measured at 3 or more standard deviation levels on the test than the probabilities of the normal distribution would predict. Some IQ scoring procedures may attempt to integrate such clusters of statistical outliers into the curve by adjusting the scores so that they better represent actual probabilities (according to Silverman) and in these cases, scores around 145 and above may actually have been notably higher, were they not so adjusted.\n\nMost IQ tests in the United States tend to use a SD-15 or SD-16 scale, meaning that one standard deviation corresponds to +/- 16 points on the IQ scale. However, European IQ tests tend to use a SD-24 or SD-25 scale, resulting in discrepancies. Therefore, an IQ of 130 (+2 standard deviations) in the U.S. might correspond to an IQ of 148-150 in Europe. Due to these differences, percentiles are more accurate measurements than IQ numbers.

This site has some good information:\nhttp://www.wilderdom.com/intelligence/IQWhatScoresMean.html\n\nQuick synopsis:\nOver 140 - Genius or near genius \n\n120 - 140 - Very superior intelligence \n\n110 - 119 - Superior intelligence \n\n90 - 109 - Normal or average intelligence \n\n80 - 89 - Dullness \n\n70 - 79 - Borderline deficiency \n\nUnder 70 - Definite feeble-mindedness

You probably can't find such a website.  I don't believe there is one.  Average IQ ranges from 85 to 115, low average to high average.

Um, I thought something like 180 was a very high IQ. 110? How about "not stupid?"

average iq is 100 , it is measured and adjusted to your age. So, I.Q. of 120 is above normal.

I don't think that there is one "best" IQ test. The best test really depends on what you want to use the results for.\n\nIn my view the best single IQ test is the Woodcock-Johnson Tests of Cognitive Abilities, third edition. It gives a reliable global score (IQ) but gives lots of information about cognitive processing skills.\n\nThe Wechsler Scales (one for adults, one for children) are fine if all you want is an overall IQ score. Not as good for breaking down different skills.\n\nThere are a bunch of shorter tests that can give you an overall IQ estimate, but they aren't used very often when you want a "serious" IQ test for a serious purpose.\n\nWrite again or edit your question with the specific reason that you are interested in IQ tests and perhaps we can come up with a more specific answer.

An i.q. score of 117 is in the high average range with a 90 to 109 being average. \n\nDescriptive Classifications of Intelligence Quotients\n \n \n \nIQ\n Description\n % of Population\n \n130+\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%\n \nI hope this helps!

According to the Wikipedia, The average IQ score is 100 by definition. \n\nIn terms of improving the IQ, a large amount of one's IQ is predetermined by genetic factors with the environment playing a role as well. The article says IQ can be improved by reading regularly and using the mind (problem solving, critical thinking, etc.).

It's just a guess.  Keep in mind too, that intelligence tests don't score that high anyway.  The Wechsler tests (WISC-IV, WAIS-III) go up to an IQ of 145 and the Stanford-Binet goes to 150.   (So when you see actors on talk shows that they were tested when young and had an IQ over 200- they are lying.)  IQ tests have these ceiling limits because it would not make financial sense to invest the money to develop items that could discriminate between individuals with higher IQ's, and it would be too difficult to individuals with higher IQ's to use in the norm group.

It is around average.  Unless it was one of those "online IQ tests," they tend to skew it to make folks feel smart (and join $$$ programs), the average on those tends to be higher, around 115-120ish.\n\nThen again the IQ test really tests your ability to take the IQ test, so take it with a grain of salt.  In general "smart" people do better at it, but it isn't an exact measure.

An IQ is your "intelligence quotient"  115 is slightly above average.  basically in a nut shell, less than 50, a sack of hammers is smarter than you, less than 90, still dumb, above 100 you will survive, above 110, you can converse with most people, above 130, you will succeed at most things you do, above 150, join Mensa, because you a smart MF.

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.

The average IQ of a 15 year old is 100. IQ scores are age adjusted, so the average is always 100 for the most commonly used IQ scales. The average range, and IQ should always be thought of as a range, not an exact score (IQ tests are not perfectly accurate) is really more like 90-110.

The average IQ is defined to be 100. most people range from about 85 to 115. The distribution of IQ scores lies on a Bell curve. It has been noted that the average IQ worldwide seems to have been rising at a rate of about 3 points per decade, so tests are periodically renormalized so that 100 is once again the average.\n\nNote that IQ tests are designed to measure specific aspects of intelligence, and there are forms and manifestations of intellect that are not indicated by one's IQ score.

That depends on the I.Q test ,since they are different in\nthe concept of calculating the I.Q .\nMost of them using a scale of 200 points ,in this case 100\npoint represent the average of the people even 90 or 110 \nstill in the average ,125 to 140 you are high intelligent \nmore than 140 ,talented.You can score up to 200.
