Document Summary

Check test-retest reliability which compares score from 2 administrations of the test: requires the computation of correlation coefficients. Invented the concepts of correlation and percentile test scores: alfred binet commissioned by french government to create a test for singling out kids in need of special training and avoid reliance on teachers potentially biased evaluations. Lewis terman at stanford expanded the binet test to create the stanford-binet test. Measured in terms of iq: mental age indicated that he or she displayed the mental ability typical of a child of that chronological (actual) age. Intelligence quotient (iq) a (cid:272)hild"s (cid:373)e(cid:374)tal age di(cid:448)ided (cid:271)(cid:455) (cid:272)hro(cid:374)ologi(cid:272)al age, (cid:373)ultiplied (cid:271)(cid:455) (cid:1005)(cid:1004)(cid:1004: wechsler intelligence scales were characterized by at least two major innovations, 1. Made scales less dependent on verbal ability: formalized computation of separate scores for verbal iq, performance (nonverbal) iq, and total iq, 2.
