US IQ Standard deviation?
US IQ standard Deviation is 16.
How is better to calculate your IQ with the basis of deviation 15 or with the basis of deviation 24?
deviation 15 is better
IQ scores are normally distributed with a mean of 100 and a standard deviation of 15 if a certain statistician has an IQ of 140 what percent of the population has an IQ less than he does?
About 98% of the population.
When your Fourteen what should you IQ be?
The average IQ for any age is 100. A slight deviation either way (95-105) is accepted as normal. Higher is "better".
What percentile of the population has an IQ of 138?
It depends on the standard deviation. IQ 138 sd 116: 1/114; IQ 138 sd 115: 1/177Have a look at this: http://www.iqcomparisonsite.com/IQtable.aspxBest wishesChristoph

Why was the deviation IQ important?
The deviation IQ was important because it helped standardize intelligence test scores by adjusting them for age. This allowed for a more accurate comparison of an individual's cognitive abilities to those of others in their age group.
What is the standard deviation of the normal IQ curve?
It is 15 points.

IQ is based on an average of 100 and a standard deviation of 15 for any group

How smart are you when your IQ's 145?
What an IQ of 145 means really depends on the test. On some tests it might means that you are smarter than 99.85% of the population, on others it might mean that you are brighter than about 80% of the population. Modern IQ tests tend to be designed to give a normal distribution of scores with 100 as the mean. A normal distribution is a bell shape, so that the closer the IQ is to 100, the more people there are with that IQ. Exactly how many for a given IQ depends on something called the standard deviation. About two thirds of people have an IQ within 1 standard deviation of 100 (the mean). For example, IQ tests commonly have a standard deviation of about +/-15. This means about two thirds of people have an IQ between 85 and 115. You might call this the average range. About 95% of people will be within two standard deviations, so using the same example, about 95% of people will have an IQ between 70 and 130. And 99.7% within 3 standard deviations. So, on an IQ test with a standard deviation of +/-15, you might say that people with an IQ of 130 or more are above average (in the top 15% or so), and if your IQ is 145 then you are in the top 0.15% of the population. However, the standard deviation depends on the test. Standard deviations on common tests range from 10 to 24. Because of this, these days psychologists tend to talk of percentile ranges when talking about IQ with a certain confidence interval. So, you would be far more likely to be told that your IQ is in the 94% percentile range with a confidence interval of 90%
Is an IQ of 117 good for 22 year old?
An IQ is designed to be age independent so your age should be irrelevant. Also, IQ scores are designed so that average IQ score for a population is 100 and the standard deviation of the scores is 15. Thus, around 9.1 % of the population will have an IQ of 117 or higher.
What is average IQ for a 13 year old?
The average of any other age, which is 100 with a standard deviation of 15. IQ scores are age adjusted.
