IQ, IQ Test and IQ Scores
You might have come across many different people already, and probably you might have noticed that there are people who can learn and master new skills pretty quickly, there are people who can remember many little details of what they have seen or experienced, there are also people who are comparatively slower in learning new skills or have difficulties to remember things.
People are different in terms of mental capacity, in other word intelligence, some are pretty smart, some are not that smart, and most are just as average. Intelligence quotient (IQ) is a score that aims to assess a person's mental capacity - the ability to acquire and apply knowledge and skills.
IQ test is a way, in which to ask a number of questions and based on answers provided by users, so as to calculate the user's intelligence quotient score.
For this IQ test, the median raw score of all users is defined as IQ 100, and scores each standard deviation up or down are defined as 15 IQ points greater or less. By this way, approximately 2/3 of the users' scores are between IQ 85 and IQ 115. About 2.5% of the users scores above 130, and 2.5% below 70.
As 'Intelligence' is such an abstract concept, no concrete measure of intelligence can be achieved, so IQ score is just an estimate of intelligence.
IQ scores have been shown to be associated with factors such as morbidity and mortality, parental social status, and biological parental IQ.
IQ scores are used for educational placement, assessment of intellectual disability, and evaluating job applicants. In research contexts, they have been studied as predictors of job performance and income. They are also used to study distributions of psychometric intelligence in populations and the correlations between it and other variables. Raw scores on IQ tests for many populations have been rising at an average rate that scales to three IQ points per decade since the early 20th century, a phenomenon called the Flynn effect.
|IQ Score ||IQ Classification|
| > 145 ||Genius|
|110â€“119 ||Above Average |
|90â€“109 ||Average |
|80â€“89 ||Below Average |
|70â€“79 ||Borderline impaired |
|55â€“69 ||Mildly Impaired |
| < 54 ||Moderately Impaired |
