Detailed explanation-1: -The term ‘IQ’ was coined in 1912 by the psychologist William Stern in relation to the German term Intelligenzquotient. At that time, IQ was represented as a ratio of mental age to chronological age x 100. So, if an individual of 10 years of age had a mental age of 10, their IQ would be 100.
Detailed explanation-2: -(a) IQ = Mental ageActual age × 100.
Detailed explanation-3: -In 1912, William Stern, a German psychologist, devised the concept of Intelligence Quotient (IQ). IQ refers to mental age divided by chronological age and multiplied by 100. IQ = M A C A × 100. The number 100 is used as a multiplier to avoid the decimal point. When the MA equals the CA, the IQ equals 100.
Detailed explanation-4: -Intelligence Quotient (IQ) is the score you get on an intelligence test. Originally, it was a quotient (a ratio): IQ= MA/CA x 100 [MA is mental age, CA is chronological age]. Today, scores are calibrated against norms of actual population scores.
Detailed explanation-5: -IQ 100 indicates that you have a median IQ, the average intelligence quotient ranges from 90 to 110, anything beyond 110 is considered as outstanding intellect or above average, and anything below 90 is labeled as dullness or borderline deficiency.
