What is formula for calculating the IQ level of students ?

Intelligence Quotient is commonly known as IQ refers to the score of a standardized test that assesses and measures human intelligence.

• The first test to measure intelligence was developed by Binet and Simon in 1905. 
• Terman in 1916 revised the test and devised the concept of Intelligence Quotient.

Key Points 

• An individual’s Intelligence Quotient (IQ) is determined by the formula given below,

\({\bf{Intelligence}}\;{\bf{Quotient}}\;\left( {{\bf{IQ}}} \right) = \frac{{{\bf{Mental}}\;{\bf{Age}}\;\left( {{\bf{MA}}} \right)\;}}{{{\bf{Chronological}}\;{\bf{Age}}\;\left( {{\bf{CA}}} \right)}} \times 100\)

• Where, Mental Age is based on intellectual development.
• Chronological Age is the number of years a person has lived.

Hence, it could be concluded that \(\frac{MA}{CA}\times 100\) is the correct formula for calculating the IQ level of students.
