What is Psychometrics?
Psychology is a diverse and exciting field. As pioneers in a relatively youthful science psychologists worldwide strive to improve every aspect of human life, from planning urban construction and zoning to human-computer interaction. Across all disciplines of psychology there is a common thread that unites all researchers and scientists in the field. This unifying discipline is psychometrics.
The following are definitions of the word Psychometrics:
- The science of psychological measurement
- The psychological theory or technique of mental measurement directed toward the mind specifically in its cognitive function
- The systematic use of tests to quantify psychophysical behaviour, abilities and problems and to make predictions about psychological performance
- The use of tests to measure skill, knowledge, intelligence, capacities, or aptitudes and to make predictions about performance
Experimental psychologists routinely devise tests to obtain data on perception, learning and motivation. Psychometricians design and administer psychological tests both to generate empirical data on mental processes and to refine their understanding of measurement techniques and the statistical analysis of results.
