  2. Generalizability theory - Wikipedia

    en.wikipedia.org/wiki/Generalizability_theory

    Generalizability theory, or G theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.e., reproducibility) of measurements under specific conditions.

  3. External validity - Wikipedia

    en.wikipedia.org/wiki/External_validity

    Research in psychology experiments attempted in universities is often criticized for being conducted in artificial situations and that it cannot be generalized to real life. [21] [22] To solve this problem, social psychologists attempt to increase the generalizability of their results by making their studies as realistic as possible. As noted ...

It is the debatable body of thought which offers an alternative to purely scientific methods in research in its search for knowledge and truth.

  6. Validity (statistics) - Wikipedia

    Reliability does not imply validity.That is, a reliable measure that is measuring something consistently is not necessarily measuring what is supposed to be measured.

  8. Construct validity - Wikipedia

    en.wikipedia.org/wiki/Construct_validity

    Generalizability – Does the test generalize across different groups, settings and tasks? How construct validity should properly be viewed is still a subject of debate for validity theorists. The core of the difference lies in an epistemological difference between positivist and postpositivist theorists.
