Crossword clues for psychometrics

Douglas Harper's Etymology Dictionary

"science of measuring mental processes," 1917, from psychometric; also see -ics.


n. (context psychology English) The design of psychological tests to measure intelligence, aptitude and personality; and the analysis and interpretation of their results.


n. any branch of psychology concerned with psychological measurements [syn: psychometry, psychometrika]


Psychometrics is a field of study concerned with the theory and technique of psychological measurement. One part of the field is concerned with the objective measurement of skills and knowledge, abilities, attitudes, personality traits, and educational achievement. For example, some psychometric researchers have, thus far, concerned themselves with the construction and validation of assessment instruments such as questionnaires, tests, raters' judgments, and personality tests. Another part of the field is concerned with statistical research bearing on measurement theory (e.g., item response theory; intraclass correlation).

As a result of these focuses, psychometric research involves two major tasks: (i) the construction of instruments; and (ii) the development of procedures for measurement. Practitioners are described as psychometricians. Psychometricians usually possess a specific qualification, and most are psychologists with advanced graduate training. In addition to traditional academic institutions, many psychometricians work for the government or in human resources departments. Others specialize as learning and development professionals.
