Explain the graph of general probability of intelligence.
✓
Answer
William Stern first formulated a formula in 1912 to measure a person's intelligence, which is as follows:
IQ (Intelligence Quotient) = mental age
(Mental Age) Chronological Age x-100
Ovi is shown in different levels of intelligence depending on the intelligence.
Classification based on intelligence first showed the term.
Many studies have been done with the help of intelligence tests on the level of intelligence in the population.
The graph drawn based on the results of these studies is seen in the form of "bells".
The graph of the classification of intelligence in the population is known as the general probability graph.
This graph shows that most of the people in the society have normal intelligence.
The proportion of people with normal intelligence (90 to 100 I.Q) is 50 percent.
While the proportion of people with more or less normal intelligence is less.While the proportion of mentally retarded (mentally challenging) and highly gifted individuals is very low in society (2.2 per cent).
