Detailed explanation-1: -The Stanford–Binet test provided an intelligence quotient (IQ) by dividing a child’s mental age by his or her chronological age and multiplying by 100. Hence the average IQ, when mental age and chronological age are equal, is 100.
Detailed explanation-2: -For the original version of the Stanford Binet, IQ was defined as: d. mental age divided by chronological age and multiplied by 100.
Detailed explanation-3: -An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.
Detailed explanation-4: -The Stanford-Binet, Fourth Edition (Thorndike, Hagen, & Sattler, 1986), is an individually administered measure of general intelligence for persons ages 2 years to 23 years 11 months.
Detailed explanation-5: -In 1912 William Stern used chronological age as a denominator to be divided into mental age, resulting in an intelligence quotient. In 1916 Lewis Terman multiplied this intelligence quotient by 100 (to eliminate the decimal places) and called the result an IQ score.
