It allowed psychologist to compare one subject's IQ with that of another subject
The average IQ of a person in the US is around 98. IQ scores are standardized to have a mean of 100 and a standard deviation of 15.
The average IQ for a student in the UK is around 100, which is considered to be in the normal range. IQ scores are standardized to have a mean of 100 and a standard deviation of 15.
The average IQ for a human being is between 95 to a 100. The average IQ for someone is 100, or the range of 90-110.
The average IQ of a United States Citizen varys each year. The average IQ for an American in the United States is around 99. Netherlands, Poland and Sweden rank as the top highest IQ nations.
The average IQ score for the general population is around 100, with most people falling within the range of 85 to 115. This range is considered to be within the normal or average intelligence level. IQ tests are designed to have a mean score of 100 and a standard deviation of 15.
US IQ standard Deviation is 16.
Intelligence quotient
deviation 15 is better
It is 15 points.

99.6% for
About 98% of the population.
Approximately 6.68% of the population falls within one standard deviation above the mean IQ score of 100, which includes an IQ of 128.
The average IQ for a student in the UK is around 100, which is considered to be in the normal range. IQ scores are standardized to have a mean of 100 and a standard deviation of 15.
IQ is based on an average of 100 and a standard deviation of 15 for any group
The average IQ for any age is 100. A slight deviation either way (95-105) is accepted as normal. Higher is "better".
An IQ test is simply a (somewhat flawed) means of assessing a person's "relative intelligence". It is important that IQ is not extremely important when working with such a measure in psychology. Now, the IQ test is designed such that scores follow a pattern known as a "normal distribution". This is not simply an expected distribution! This distribution is very important in the study of statistics, and has many applications to scientific disciplines (such as psychology). A standard deviation is essentially a measure of distance from the mean. For example, say that the average person lives to be 75, with a standard deviation of 4. This means that a person who lives to be 79 would be one standard deviation above the mean, and a person who lives to be 67 would be two standard deviations below the mean. As a table depicting the normal distribution can show, one standard deviation above the mean is at the 84th percentile, while one standard deviation below the mean is at the 16th percentile (two stds above: 97.5th, two stds below: 2.5th) This means that an IQ score of 115 is at the 84th percentile, while an IQ score of 85 is at the 16th percentile. 68% of all people are within this range, and that is "most" people.
