Validity - a test must measure what it means to measure Types of validity Content - does the test examine the behavior under scrutiny? Construct - test's ability to measure a theoretical construct like intelligence Concurrent - how well the test compares to other instruments that are intended for the same purpose Predictive (empirical) - test's ability to predict future behavior according to criteria Consequential - social implications of using tests * criterion validity - concurrent validity and predictive validity together Incremental vs. synthetic validity Incremental - process by which a test is refined and becomes more valid as contradictory items are dropped Synthetic - helper looks for tests that have been shown to predict each job element or component Convergent vs. discriminant validity Convergent - correlating test scores with an outside source Discriminant - test will not reflect unrelated variables Reliability coefficient of .70 means 70% of the score is accurate and 30% is inaccurate True variance or coefficient of determination Square the coefficient Ex: Correlation of .70 .... .70 x .70 = .49 and .49 x 100 = 49% First IQ test Alfred Binet and Theodore Simon MA/CA x 100 IQ formula replaced by SAS (standard age score) Wechsler IQ More for adults than Binet WPPSI Wechsler PS and Primary Scale of Intel. - 2-6 months to 7 years and 7 months WAIS-IV Wechsler Adult Intelligence Scale - 16-90 years Online, 60-90 min, based on neurocognitive research, verbal/perceptual/working memory/processing speed, FSIQ (full scale IQ), measures IQ from 40-160 Mean: 100 SD: 15 (16 for Stanford Binet) WISC-IV Wechsler Intel.
