Examples of psychometric test in the following topics:
-
- 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 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.
-
- Intelligence tests and standardized tests face criticism for their uses and applications in society.
- Intelligence tests (such as IQ tests) have always been controversial;Â 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.
-
- 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.

- Different statistical tests are used to test quantitative and qualitative data.
- Paired and unpaired t-tests and z-tests are just some of the statistical tests that can be used to test quantitative data.
- A t-test is any statistical hypothesis test in which the test statistic follows a t distribution if the null hypothesis is supported.
- A z-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution.
- One of the most common statistical tests for qualitative data is the chi-square test (both the goodness of fit test and test of independence).
-
- A standardized test is a test that is administered and scored in a consistent manner.
- A standardized test is a test that is administered and scored in a consistent manner.
- Finally, critics have expressed concern that standardized tests may create testing bias.
- Testing bias occurs when a test systematically favors one group over another, even though both groups are equal on the trait the test measures.
- Critics allege that test makers and facilitators tend to represent a middle class, white background and standardized testing matches the values, habits, and language of the test makers.

- Convergence tests are methods of testing for the convergence or divergence of an infinite series.
- Convergence tests are methods of testing for the convergence, conditional convergence, absolute convergence, interval of convergence, or divergence of an infinite series.
- When testing the convergence of a series, you should remember that there is no single convergence test which works for all series.
- Here is a summary for the convergence test that we have learned:
- The integral test applied to the harmonic series.
