The equation used to calculate a person's IQ score is Mental Age / Chronological Age x 100. On most modern IQ tests, the average score will be 100 and the standard deviation of scores will be 15.

If you have a high IQ score, it means your reasoning and problem-solving abilities are better than average and may signal intellectual potential. An IQ of 70 or below may indicate limited intellectual functioning.

According to modern IQ standards, which place normal intelligence within the 90–109 range, a genius is often defined as anyone boasting a 130 or above score. Informally, polymaths—who excel in multiple fields—and experts are often considered geniuses.

IQ tests measure a variety of skills like working memory, fluid reasoning, verbal comprehension and more. But he notes the science suggests IQ tests are still not well equipped to provide meaningful scores for these separate abilities, and should be interpreted only as measuring someone's overall general intelligence.

If you have a high IQ score, it means your reasoning and problem-solving abilities are better than average and may signal intellectual potential. An IQ of 70 or below may indicate limited intellectual functioning. However, IQ alone doesn't tell the whole story.

IQ Scale Range Your IQ is a measure of your intelligence. ... 140 and over : If you have an IQ range of 140 and over, it means you are a genius or almost genius. 120 - 139 : With an IQ of 120 to 139, it means you have very superior intelligence and your intelligence is better than most.

IQ, or intelligence quotient, is a measure of your ability to reason and solve problems. It essentially reflects how well you did on a specific test as compared to other people of your age group. While tests may vary, the average IQ on many tests is 100, and 68 percent of scores lie somewhere between 85 and 115. 1﻿

IQ tests measure current academic abilities -- not any sort of fixed, innate intelligence. More specifically, the best-known IQ battery, "Stanford-Binet 5," measures Fluid Reasoning, Knowledge, Quantitative Reasoning, Visual-Spatial Processing, and Working Memory.

An IQ test score is calculated based on a norm group with an average score of 100 and a standard deviation of 15. The standard deviation is a measure of spread, in this case of IQ scores. A standard devation of 15 means 68% of the norm group has scored between 85 (100 – 15) and 115 (100 + 15).

The average IQ score is always 100, and your personal score tells you your IQ ranking compared to that. IQ scores are based on comparisons with other people who took the test: the norm group. As 100 is the average score, your score tells you how your IQ score ranks compared to other people.

An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence.
1418332
An intelligence quotient or an IQ is a numerical score on an intelligence test. It shows how much someone's intelligence score, measured by the test compares with other people of the same age.

A person's IQ score was originally calculated by dividing a person's mental age by their chronological age and then multiplying by 100. Or, MA ÷ CA × 100. Chronological age was simply the child's biological age or how old the child was. Mental age was derived via an intelligence test and seeing how the child scored.

['First, determine n, which is the number of data values.', 'Second, calculate the arithmetic mean, which is the sum of scores divided by n. ... ', 'Then, subtract the mean from each individual score to find the individual deviations.', 'Then, square the individual deviations.']

The first thing to know about IQ is that it is a composite score made up of the results of many different tests of reasoning, memory, acquired knowledge, and mental processing speed. These sub-scores are totaled, and are then compared with those of the rest of the population.

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.
