What are Psychological Tests and Measurements?

Psychological tests (known as mental measurements, psychological instruments, psychometric tests, inventories, rating scales, are standardized measures of a particular psychological variable such as personality, intelligence, or emotional functioning. They often consist of a series of questions that subjects rank as true or false, or according to a Likert-type scale (agree, somewhat agree...), however tests can use written, visual or verbal methods.

Many tests are commercially published. One well-known commercial test is the Myers-Briggs Type Indicator. Commercial or published tests may need to be purchased from the publisher, and publishers may require proof that users have the professional credentials to administer the test.

In addition to commercial tests, there are countless unpublished tests that researchers design for particular studies in psychology, education, business and other fields.
