比率智商与离差智商的异同（The difference between ratio IQ and deviation intelligence quotient）

比率智商与离差智商的异同（The difference between ratio IQ and deviation intelligence quotient） In order to accurately express a level of intelligence, intelligence experts put forward the concept of measurement from the IQ, i.e. a person in his age in a position, namely through the calculation of the subjects from the average number of standard deviation to measure, which is also known as deviation IQ, IQ (IQ). For example, two different age adults, a persons intelligence test scores higher than the average value of the fractional age group, another test score is lower than the average age group, then we conclude: the IQ of the former higher than the latter. At present, most intelligence measures use the differential intelligence quotient (IQ) to express ones intelligence level. The quotient distribution of the population. In the typical modern intelligence tests, the average IQ of the establishment of the subject of the population was 100, according to the statistics principle, half of the population is 90110, including IQ, IQ in 90 to 100 and 100-110 people each accounted for 25%. IQ in 110-120 accounted for 14.5%, accounting for 7% of the 120130 IQ, 130-140 people accounted for 3%, the remaining 0.5% IQ above 140, while 25% of people under 100 points IQ. It is easy to distinguish the difference of intelligence after the intelligence test of intelligence and intelligence is low. They found a high IQ (IQ above 130) and very low IQ people (IQ below 70) are few, intellectual medium or close to medium (IQ 80 to 120) between the total population of 80%, more than normal intelligence, we call those extraordinary intelligence, wisdom below the normal force, we call low intelligence. We adopted the American psychologist Wechslers intelligence scale, which was revised by the Hunan Medical University Gong Yaoxian and so on, and formulated the Chinese norm. Now we can examine 6-16 year old children and adults over the age of 16. By understanding the psychological measurement of their int
