Our test currently has aglobalmean of99.59and a standard deviation of14.98among all the people who have challenged their cognitive abilities with our test. We aim to calibrate the test to a mean of100and a standard deviation of15to provide every test taker with the most accurate results possib...
For an IQ test to be considered reliable, it must produce results following a Gaussian distribution (mean of 100, standard deviation of 15) when administered to a representative sample of the population. We have published a study showing the reliability of the International IQ Test, based on ...
Most tests are standardized so that their mean score is 100 and their standard deviation is 15 making the calculation of a percentile trivial through the use of the normal distribution CDF. Some tests use a different standard deviation: 16, 24, etc. which is why our IQ calculator allows you...
IQ Graph of intelligence quotient (IQ) as a normal distribution with a mean of 100 and a standard deviation of 15. The shaded region between 85 and 115 (within one standard deviation of the mean) accounts for about 68 percent of the total area, hence 68 percent of all IQ scores. ...
Answer to: IQ scores on the WAIS test approximate a normal curve with a mean of 100 and a standard deviation of 15. What IQ score is identified...
IQ scores follow a standard bell curve for anormal distribution. The curve is distributed usingstandard deviationsfrom themean. Standard deviation is a measure of variability in a population. When calculating percentiles for IQ scores, a standard deviation of 15 is used. ...
But emotional quotient, which is a more important role in the development of the day after tomorrow, because of the number of values and practical ability of the social pressure and change. High IQ does not mean that EQ is high, and even some gifted children's IQ is very high, but due...
Over the next centuries, IQ test development and IQ testing generally would evolve considerably, with the biggest improvement coming in the early 20thCentury when the old MA/CA equation would be replaced with that modern statistical techniques involving mean and standard deviation. ...

Standardized IQ tests are designed so that the exact average (mean) IQ score in the general population is 100. An ‘averageIQ score’or‘normal IQ score’can be defined as a score between 85 and 115 – between plus and minus one standard deviation from the average. (See the table below...
