AP PSYCHOLOGY

Detailed explanation-1: -Historically, IQ was a score obtained by dividing a person’s mental age score, obtained by administering an intelligence test, by the person’s chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score.

Detailed explanation-2: -IQ tests are composed of sub-tests that measure more specific abilities. Scores on these sub-tests are combined to yield measures of verbal and nonverbal abilities, processing speed and working memory, as well as a Full Scale IQ score.

Detailed explanation-3: -What is IQ? IQ, (from “intelligence quotient”), a number used to express the relative intelligence of a person. It is one of many intelligence tests.

Detailed explanation-4: -An Intelligence Quotient, or IQ, is a measure of what psychologists call our “fluid and crystallized intelligence.” Put simply, an IQ test measures your reasoning and problem-solving abilities.

Detailed explanation-5: -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.
