Document Summary

Standardization: uniform procedures in the administration and scoring of a test. Test norms: where specific scores rank in relation to other scores on that test. Standardization group: group that is compared to (normed on population that is like the people taking the test) Reliability: consistency (score shouldn"t change, regardless of when the test is taken in one"s lifetime) Correlation coefficient: tests should be close to +1 (however, very few tests are like this because very few humans manage to take tests under the exact same conditions, so scores can vary) Validity: ability of a test to measure what it is supposed to measure. Content validity: is test content measuring relevant information about subject area. Criterion-related validity: correlation between two things (for example, performance between training and testing should be similar) Construct validity: looks for evidence proving that test measures the construct it should be testing (for example, do iq tests really test intelligence?)
