Intelligence Quotient

IQ stands for Intelligence Quotient. It is a measurement of human’s intelligence and expressed in a number. Thus, IQ is a score derived from a set of tests developed to measure a person’s cognitive abilities in relation to their age group. It was first coined by the German psychologist William Stern in 1912 to identify students that needed special help with school curriculum.

A person’s IQ can be calculated by having the person take an intelligence test. The average IQ is 100. If someone achieves a score higher than 100, that person is smarter than the average person, and a lower score means he/she is less smart.


IQ Formula:

It is calculated by first dividing the mental age of an individual by physical health and then multiplying it by 100.


IQ Instance:

Take an example of 20-year-old individual answers the questions like an average 20-year-old.

  • Age of the person is: 20 years
  • Age of the brain (typical or average): 20 years

So, we can also conclude that the average IQ of an individual is 100.
