IQ, or intelligence quotient, is a ratio of the mental age to chronological age. In other words, it’s a measure of how well someone can use information and logic to answer questions or make predictions. At its most basic, IQ is simply a score on an intelligence test. The best-known IQ test was developed by French psychologist Alfred Binet in 1905 and revised in 1916. His original purpose was to find a way to identify children who would need additional help in school — the ones who might otherwise fall behind their peers and be considered “backward.”
In short, the idea of IQ is supposed to gauge how well someone can use information and logic to answer questions or make predictions. The most famous IQ test was developed by French psychologist Alfred Binet and revised in 1916. But as a concept, IQ has been around for much longer. The Greek philosopher Aristotle, for example, may have been the first person to note that people who were good at math tended to be good at other things — like memory and reasoning — as well.
The history of the term “IQ” is less clear. Some people believe that William Stern coined the term in 1912 when he began publishing his theories about intelligence testing. Others think that psychologist Lewis Terman came up with it.
What is a good IQ score?
The average IQ score is always 100 and your personal score tells your IQ ranking compared to the average. IQ scores are based on the 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.
When you get your test results back, look at where you fall on the IQ scale. If your result is higher than 100, then it means that you have a higher IQ than 97% of the population. If it’s between 90 and 110, this indicates that your score is near average; most people fall into this category. Elon Musk’s IQ is also good. If it’s between 80 and 90, then you have an average or below-average IQ; this is so because most of us fall into these categories. If your result falls at or below 80 points, then you have an extremely low intelligence quotient; only about 2% of the population will end up in this category.
As for why we use these numbers—all people tend to rank themselves pretty high when asked to do self-assessments, but a lot of researchers agree that using numbers makes these assessments more accurate. It also helps give a concrete number to deal with when trying to compare one person’s intelligence with another. Also know about Elon Musk’s IQ.
How to calculate IQ level?
The intelligence quotient can obtain by the equation MA/CA=IQ, where MA is the mental ages and CA is chronological age.
The mental age is a measure of the mental development of an individual. The chronological age is a measure of the physical or actual development of an individual. By using the ratio between these two measures, we can calculate the intelligence quotient. In order to get the most accurate result, it is important to take into account the level of education of the person, as well as other environmental factors. So in order to determine your IQ level, you first need to know your mental and physical ages and then perform the calculation above.
There are many ways to calculate IQ levels, so there is no set standard for this calculation. Most commonly, though, the intelligence quotient will be calculated based on performance on intelligence tests such as Wechsler Adult Intelligence Scale (WAIS), Raven’s Progressive Matrices test, or Stanford-Binet Intelligence Scale test, among others.
