Psychometry - Reliability, Validity, Item Analysis, Normative Data - Current research/trends

test psychological degree representative

Psychometry or psychometrics is a field of psychology which uses tests to quantify psychological aptitudes, reactions to stimuli, types of behavior, etc., in an effort to devlop reliable scientific models that can be applied to larger populations.


Currently many new psychometric theories and statistical models are being proposed that will probably lead to changes in test construction. In addition, the use of computers to administer tests interactively is on the rise. Finally, studies of test bias and attempts to diminish it will likely increase in response to lawsuits challenging various occupational and school decisions based on test results.
