IQ is a quantitative indicator of human intelligence level. It was put forward by German psychologist Steen in 19 12. IQ is the abbreviation of IQ, which is expressed in English. IQ is the quotient of intellectual age divided by physiological age. The calculation formula of IQ is as follows: IQ = IQ = ma÷÷÷C.A×100, and IQ represents human intelligence. The higher IQ means smarter. Physiological age refers to the actual age of a child after birth. Intellectual age or psychological age is the age measured according to intelligence measurement.
Intellectual age can only represent the absolute level of intelligence, but not the intelligence level of children of different physiological ages. For example, a child is 5 years old physically and 6 years old intellectually, while b child is 10 years old and intellectually10 years old. The intellectual age of both children is older than their physiological age 1 year, so their intelligence is more difficult. Their intelligence level can be relatively compared by IQ. A child's IQ is 5/6× 100= 120, and B child's IQ is110×100 =1. From the IQ of children A and B, it can be considered that the intelligence level of children A is higher than that of children B. ..
Generally, people classify the intelligence level as follows: those whose IQ is above 140 are called geniuses; Iq 120- 140 is the best; Iq 100, 165438, 120 is the best; The IQ of 90-65438 is the best.
