Document Summary
Does the test measure what it is supposed to measure. Face validity- looks like it measures exactly what it"s supposed to measure. Convergent validity- if it converges with some other measure it"s supposed to go with. Discriminant validity- different from thing not supposed to measure. Predictive validity- predicts things it"s supposed to predict. Measure once, measure twice, get the same result (test-retest reliability) Split up test, both parts correlate well (split-half reliability) Expected reliability depends on possibility of change in variable. All these issues crucial to understanding intelligence. We all know what it is but difficult to define formally. The ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience (gottfredson, 1997) Early 1900s, france needed help in its public schools. Wanted to identify children who needed remedial education. Alfred binet- wanted to identify the kids who needed help. Binet viewed intelligence as a general ability.
