Thus, external validity is generally concerned with the generalizability of External validity is a question of the generalizability of the results. If we replicate the study using different a sample, the study should still share similar results. External validity assesses how the research relates to the real-world. In simple terms, validity is the reliability of the study. And knowing the difference between internal vs external validity is crucial. A good example would be a test of strength is measuring just that, strength, and nothing else (such as endurance or stamina).
2018-12-19 The external validity of a particular study changes as more research is conducted in the same area; other studies may demonstrate that it was not very generalizable (that is, its external validity was weak) or that it proved to be very consistent in different settings (making its external validity strong). External Validity: External validity refers to one of the measurements of the usefulness of studies and assessments in psychology. This complements and can be contrasted with internal validity Relationship between internal validity and external validity Remember this relationship from the previous chapter: as one goes up, the other goes down… as a general rule… As we implement more and more controls to reduce confounds (i.e. increase internal validity) we are making the experiment more and more artificial and External validity is threatened when a examine doesn’t take note of the interactions of variables in the true world. Pre- and post-test results: When the pre- or post-test is ultimately associated to the impact seen within the examine, such that the cause-and-effect … External Validity.

A lack of understanding may doom your study, while strong external validity makes getting your dissertation accepted and/or article much easier to get published. External validity is one the most difficult of the validity types to achieve, and is at the foundation of every good experimental design. Many scientific disciplines, especially the social sciences, face a long battle to prove that their findings represent the wider population in real world situations. External validity is addressed by delineating inclusion and exclusion criteria, describing subjects in terms of relevant variables, and assessing generalizability.

Time affects our ability to make generalisations. When making generalisations that involve time, we need to not only think about the threats to external validity that arise from making generalisations across time, but also the fact that time is a part of the treatment (i.e., intervention) within quantitative research (e.g., a 15 week teaching period versus a 3 year
External validity is important in psychology studies - it measures the extent to which an experiment can be generalised to create general rules that can be applied in other, real life situations.
