Key Points

 Intelligence Quotient is the measure of a child's ability to reason and solve problems. IQ is correlated either directly or indirectly with problem-solving and educational performance.

Intelligence Quotient (IQ) can be obtained by the equation (MA/CA) * 100 = IQ, where MA is mental age and CA is chronological age.

• Mental Age is the measure of the intellectual level at which an individual functions; for example, someone described as having a mental age of 8 years would be functioning at the level of an average 8 years old.
• Chronological Age is the number of years a person has been alive

IQ Rating Scale:

Hence, it can be concluded that if the educational quotient of a child is less than 70, that child can be said to be a backward child.
