What is psychometrics?
Psychometrics is a science that deals with planning methods of research and analyzing the results to quantify and appraise human competence and abilities. Psychometricians are experts in assessing and evaluating an individual’s strengths, weaknesses and competencies. They are trained in the science of building tests to assess human traits, including those which measure competence in a given profession. When psychometric principles are applied by a psychometrician to develop an exam it signifies the difference between a test that is merely a bunch of questions about a given topic and a tool that accurately measures and documents knowledge and skill levels related to the test domains. In certification exam development, a psychometrician uses scientific methodology to ensure that the four categories of valid test development (validity, reliability, cut score, and fairness) are appropriately adhered to. Correctly applied psychometrics provides precise measures of the test-taker’s competenc
Psychometrics is a field in which practitioners attempt to measure psychological response like emotion, intelligence, or other mental-based abilities, of individuals. An individual’s test results are then compared to an average group’s performance in these areas. A key example is the typical IQ test, which measures intelligence quotient. The test score you receive on an IQ test is compared to the body of people who have taken the test previously, and a number is assigned (the score) as your IQ number. Theoretically, a higher number IQ translates to greater intelligence. Since the development of the IQ tests, psychologists have used psychometrics in a variety of ways to look at people’s strengths, their weaknesses, and areas in which they may be disabled or gifted. Psychometrics develops what are called “instruments” in order to make these measurements. Actually instruments are more likely to be tests of a variety of types; so the term sounds a little more concrete than it really is. Th
An introduction to Psychometrics One 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. Psychometrics, being concerned with the design and analysis of research and the measurement of human characteristics, has enjoyed a history of rapid growth and development since its origins with the work of Binet in France and Spearman in England, and the earlier efforts of Galton and his anthropometric laboratory. The field of psychometrics has been the genesis of intelligence testing, personality testing, and vocational testing, and has contributed to the emergence of new approaches and methods to psychological measurement based on the demands of society and
The word “psycho” refers to the mind, where “metric” is a term used to measure. Psychometrics is basically a form of testing to find out the strengths and weaknesses of a candidate and is generally used by in their selection process. Depending on the employer, these tests are often used to assess suitability. The selection process often takes place before a candidate interview, but this will often depend on the preference of the employer. A Psychometric test, is unlike any normal test you would take under exam conditions, so it is not possible to revise for questions that may be asked in these kind of tests. You can however help train your mind in preparation for a Psychometric test. These kind of tests are used to measure your aptitude and/or personality, and find out how you would respond in certain conditions. There are two primary forms of test. The first is known as an “Aptitude Test” and the second is known as a “Personality Questionnaire”. Aptitude Test These tests are also refe
