What is the LQ question?

English noun: intelligence quota is abbreviated as IQ.

Definition of IQ

IQ is IQ. Cleverness is usually called wisdom, also called cleverness. It is the ability of people to know objective things and use knowledge to solve practical problems. Intelligence includes many aspects, such as observation, memory, imagination, analysis and judgment, thinking ability and adaptability. The level of intelligence is usually expressed by IQ, which is used to express the level of intellectual development.

IQ is IQ (short for IQ). Generally speaking, it can be understood as intelligence, specifically referring to the ability of numbers, space, logic, vocabulary, memory and so on. In a sense, IQ is like computer hardware such as CPU. A person with high IQ can do very complicated things in a short time. Just as Pentium and Centrino CPU can run large software such as Windows XP, 386 and 486 can only run small software such as DOS.

IQ classification

There are two kinds of IQ, one is the ratio IQ, and the age of intelligence is equal to the age of foot. If a person's intellectual age is equal to his actual age, then his IQ is 100, indicating that his intelligence is medium. The other is biased IQ, which takes the ratio of a person's test scores to the average intelligence of normal people of the same age as IQ. Nowadays, most intelligence tests use wandering IQ.

In order to accurately express a person's intelligence level, intelligence measurement experts put forward the concept of deviation IQ, that is, measuring a person's correct position in his age, that is, by calculating how many standard deviations the subjects deviate from the average, which is called deviation IQ, also known as IQ.

(2) For example, for two adults of different ages, one person's intelligence measurement score is higher than the average score of the same age group, and the other person's test score is lower than the average score of the same age group, then we can draw the conclusion that the IQ of the former is higher than that of the latter.

(3) At present, most of the intelligence measurements use biased IQ to express a person's intelligence level.

④ Distribution of population IQ.

In a typical modern intelligence test, if the average IQ of the subject population is 100, according to certain statistical principles, the IQ of half the population is between 90- 1 10, and the IQ is between 90- 100 and 165438+. 1 10- 120 accounted for 14.5%, 120- 130 accounted for 7%,130-10.

⑤ Extraordinary intelligence and low intelligence.

After the appearance of intelligence test, it becomes easier to distinguish intelligence differences. It is found that a few people have extremely high IQ (above 130) and extremely low IQ (below 70), and about 80% of the total population have average or near-average IQ (between 80- 120). Those with higher intelligence than normal are called abnormal intelligence, while those with lower intelligence are called abnormal intelligence.
