intelligence quotient (IQ). defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 [thus, IQ = (ma/ca) x 100]. On contemporary intelligence tests, the average performance for a given age is assigned a score of 100.efined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 [thus, IQ = (ma/ca) x 100].

If a five year old took his test, and had the mental age of a three year old, then the school would work harder with him to raise his intelligence. Louis Terman, a Stanford professor, brought this idea to the United States and created the Stanford-Binet IQ test.IQ stands for intelligence quotient.A person's IQ score is computed by dividing a person's mental age by their chronological age and multiplying by 100. So if a 7 year old takes an IQ test and scores the mental age of a 7 year old; 7/7=1 times 100= an IQ of 100.Thus an average IQ would be 100.f a five year old took his test, and had the mental age of a three year old, then the school would work harder with him to raise his intelligence.
