IQ is a number meant to measure people cognitive abilities (intelligence) in relation to their age group. An I.Q between 90 and 110 is considered average; over 120, superior. Roughly 68% of the population has an IQ between 85 and 115. The average range between 70 and 130, and represents about 95% of the population. A score below 70 may indicate problems in understanding the iQ questions or soem type or retardation, and a score above 130 may indicate intellectual giftedness. 1% of the population has an IQ of 136 or higher.

The current scoring method for all IQ tests is the deviation IQ. In this method, an IQ score of 100 means that the test-taker's performance on the test is at the median level of performance in the sample of test-takers of about the same age used to norm the test.

For example, a mental age score of thirteen years and zero months for a test-taker with the chronological age ten years and zero months results in a quotient of 1.3 after doing the division. The division result was then multiplied by 100 so that scores could be reported without decimal points.

High IQ societies ask for certain percentile scores on IQ tests for you to be eligible to join them. Mensa asks for scores at the 98th percentile or higher. For a list of the selection criteria of other societies, click here.

Free IQ Test. A typical way of determining the relative intelligence of different people, is to give them an IQ test and compare the scores.. Boys at the top of the food chain either by birth or because their older siblings died score higher on IQ tests than their younger brothers..

IQ classification is the practice by IQ test publishers of labeling IQ score ranges with (somewhat subjective) category names such as superior or average. There are several publishers of tests of cognitive abilities.

An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance one standard deviation below the median, and so on. Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure.

50% of IQ scores fall between 90 and 110. 70% of IQ scores fall between 85 and 115. 95% of IQ scores fall between 70 and 130. 99.5% of IQ scores fall between 60 and 140. Low IQ & Mental Retardation. An IQ under 70 is considered as mental retardation or limited mental ability. 5% of the population falls below 70 on IQ tests. The severity of the mental retardation is commonly broken into 4 levels: 50-70 - Mild mental retardation (85%).

It compares people of the same age or age category and assumes that IQ is normally distributed, that the average (mean) is 100 and that the standard deviation is something like 15 (IQ tests sometimes differ in their standard deviations).

IQ = (MA/CA) * 100. The intelligence quotient was equal to 100 times the Mental Age divided by the Chronological Age. For example, if a certain child started reading, etc., at the age of 3 (CA) and average children start reading, etc., at the age of 6 (MA), the child would get an IQ score of 200. (Such a score is very, very rare).
