How to measure a person's IQ index?

The IQ test includes 1 1 items, including common sense, understanding, arithmetic, similarity, memory, words, images, building blocks, permutation, puzzles and symbols. The whole test takes about an hour, and it takes about an hour to summarize, analyze and write a test report.

: 1. There are two kinds of IQ, one is ratio IQ, and intelligence age ÷ full-time age = IQ. If a person's intellectual age is equal to his actual age, then his IQ is 100, indicating that his intelligence is medium.

2. 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 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.

4. For example, 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 conclude that the IQ of the former is higher than the latter.

After the advent of intelligence test, it is easy to distinguish the differences of intelligence. It is found that people with extremely high IQ (IQ 130 or above) and extremely low IQ (IQ below 70) are a minority.

6.？ About 80% of the population has average or near-average intelligence (IQ is between 80- 120). Those with higher intelligence than normal are called abnormal intelligence, while those with lower intelligence are called abnormal intelligence.
