world population falls in that range. That means about every second person falls under that category. This isn't a coincidence. IQ tests are constructed in that way. Below you will see the average IQ scores for some categories. These values are what we have calculated on this website so ...

Similar in nature to today's age equivalent scores, mental ages were calculated by finding the typical score obtained by children at each age level on a test; children earning the median raw score for a given age were assigned that age as a mental age score. In 1914, William Stern first...
Its strengths were that it could be used with respondents of all ages from early childhood to old age and was of such a length that it could reasonably be administered in homes, schools, and workplaces. Scores are converted into age adjusted IQ according to Raven's Matrices. ...
Not deliberately, I mean, but she cheated nonetheless. Her IQ scores cannot really be equated with Terman’s IQ scores. It’s not just that one set is too high or too low relative to the other, but that the two sets don’t really measure the same thing, at least not most of the ...
This is the equivalent of 7 or 8 points on an IQ test, or a ascent from the 30th to the 50th percentile on test scores. The above reports demonstrate that schooling is an important factor that affects intelligence. By schooling, one can improve knowledge of specific facts for intelligence ...
American Mensa, often referred to as US Mensa, has its own qualification exam that doesn’t give a score equivalent to the scores used by the other Mensa chapters. Every qualifying intelligence test for Mensa must be taken in person; there are no online tests that the organization accepts. ...
Normal distribution of IQ scores The IQ Test Labs scale is equivalent to the Wechsler scale. (mean=100 and standard deviation=15) The bell curve (also called a "normal curve" or "normal distribution") is a graph that shows approximately how much of the population falls into each IQ range...
1. A number seen as a measure of a person's intelligence, usually representing the person's score on an intelligence test as expressed in relation to the scores of others who have taken the same test, with the average score set at 100. 2. The ratio of tested mental age to chronological...
First, we examined the means (M) and standard deviations (SD) of the PISA 2018 scores, the equivalent IQ scores, parental education, and a set of psychological measures used in the study by country. These results are in the appendix. Second, a correlation analysis was conducted with the va...
