Document Summary
Iq does not prevent you from making mistakes. Obviously, intelligence is not measured by one thing. Psychometric approach: devise tests to measure a person"s cognitive level relative to others in a population. Galton devised correlation procedure to examine relation between simple measures of intelligence. Simple measure of intelligence did not correlate with social class. Binet and simon devised a test to measure intellectual development in children. Devised mental age concept : ma = average age at which children achieve an actual score. It measures very specific forms of intelligence. It measures based on how well an individual does in school (tests school subjects) To allow for comparison of test scores among persons, l. terman devised the concept of intelligence quotient (iq): iq = (ma/ca) x 100. Average score is arbitrary and goes up every year. If we get below 85-70 it"s called borderline insanity. Iq test scores predict ability to succeed in school (valid use)
