psychometric test

Examples of psychometric test in the following topics:

• Case Studies

  • Case studies use techniques such as personal interviews, direct observation, psychometric tests, and archival records to gather information.
  • Rather, they can provide extensive information for the development of new hypotheses for future testing, or about a rare or otherwise hard-to-study event or condition.
  • One major advantage of the case study in psychology is the potential for the development of novel hypotheses for later testing.
  • Case studies also cannot test hypotheses.

• IQ Tests

  • IQ tests attempt to measure and provide an intelligence quotient, which is a score derived from a standardized test designed to access human intelligence.
  • There are now several variations of these tests that have built upon and expanded the original test, which was designed to identify children in need of remedial education.
  • Scores on IQ tests tend to form a bell curve with a normal distribution.
  • IQ tests are a type of psychometric (person-centric) testing thought to have very high statistical reliability.
  • Currently, most tests tend to measure both verbal and performance IQ.

• Controversies in Intelligence and Standardized Testing

  • Intelligence tests and standardized tests face criticism for their uses and applications in society.
  • Intelligence tests (such as IQ tests) have always been controversial; critics claim that they measure factors other than intelligence.
  • They also cast doubt on the validity of IQ tests and whether IQ tests actually measure what they claim to measure—intelligence.
  • The field of psychometrics is devoted to the objective measurement of psychological phenomena, such as intelligence.
  • IQ tests are often criticized for being culturally biased.

• Validity and Reliability of Personality Assessments

  • When it comes to examining the validity and reliability of personality measures, some have better psychometric properties than others.
  • Because of this, objective tests are said to have more validity than projective tests.
  • In contrast to objective tests, projective tests are much more sensitive to the examiner's beliefs.
  • In the Thematic Apperception Test, however, which involves open-ended storytelling, standardization of test administration is virtually nonexistent, making the test relatively low on validity and reliability.
  • However, it was found that test bias limited their usefulness.

• Standardized Tests

  • Standardized tests are identical exams always administered in the same way so as to be able to compare outcomes across all test-takers.
  • Standardized tests are assessments that are always administered in the same way so as to be able to compare scores across all test-takers.
  • Standardized tests are usually created by a team of test experts from a commercial testing company in consultation with classroom teachers and university faculty.
  • Standardized tests are perceived as being "fairer" than non-standardized tests and more conducive to comparison of outcomes across all test takers.
  • Some recent standardized tests incorporate both criterion-referenced and norm-referenced elements in to the same test.

• Personality Testing in the Workplace

  • Using personality tests as hiring or evaluation tools in the workplace is very controversial.
  • Employment testing is the practice of administering written, oral, or other tests as a means of determining the suitability or desirability of a job applicant.
  • The premise is that if test scores are found to correlate with job performance, then it is economically useful for the employer to select employees based on scores from that test.
  • A major criticism of many personality tests is that because they are sometimes based on narrow samples in which white, middle-class males are over-represented, they tend to skew test results toward this identity.
  • As mentioned above, tests like the MMPI are often useful in identifying mental illness.

• History of Intelligence Testing

  • He created and published the first IQ test in the United States, the Stanford-Binet IQ test.
  • Cattell created the Culture-Fair Intelligence Test.
  • Another supposedly culture-fair test is Raven's Progressive Matrices, developed by John C.
  • This test is a nonverbal group test typically used in educational settings, designed to measure the reasoning ability associated with g.
  • Because of the Flynn effect, IQ tests are recalibrated every few years to keep the average score at 100; as a result, someone who scored a 100 in the year 1950 would receive a lower score on today's test.

• Overview of Personality Assessment

  • Psychologists measure personality through objective tests (such as self-reports) and projective measures.
  • The most common of these methods include objective tests and projective measures.
  • An objective test is a psychological test that measures an individual's characteristics in a way that isn't influenced by the examiner's own beliefs; in this way, they are said to be independent of rater bias.
  • The most common form of objective test in personality psychology is the self-report measure.
  • During the test, participants are shown the inkblots and asked what each one looks like.

• The Psychology of Recruiting and Selecting Employees

  • Common selection tools include ability tests, knowledge tests, personality tests, structured interviews, the systematic collection of biographical data, and work samples.
  • The main goal of these tests is to predict job performance, and each test has its own relative strengths and weaknesses in this regard.
  • Another tool used for selection is personality testing.
  • Unlike psychomotor ability tests, physical ability tests measure gross motor skills, such as lifting and running.
  • When we ask if a measure has good construct validity, we're asking, "does this test the thing we are interested in testing?"

• Descriptive Research

  • Descriptive research refers to the measurement of behaviors and attributes through observation rather than through experimental testing.
  • Research studies that do not test specific relationships between variables are called descriptive studies.
  • Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables.
  • Experimental research goes a step further beyond descriptive and correlational research and randomly assigns people to different conditions, using hypothesis testing to make inferences about how these conditions affect behavior.
  • Correlational and experimental research both typically use hypothesis testing, whereas descriptive research does not.
