  2. Replication crisis - Wikipedia

    en.wikipedia.org/wiki/Replication_crisis

    Study replication rates were 23% for the Journal of Personality and Social Psychology, 48% for Journal of Experimental Psychology: Learning, Memory, and Cognition, and 38% for Psychological Science. Studies in the field of cognitive psychology had a higher replication rate (50%) than studies in the field of social psychology (25%). [77]

  3. Reproducibility Project - Wikipedia

    en.wikipedia.org/wiki/Reproducibility_Project

    Brian Nosek of University of Virginia and colleagues sought out to replicate 100 different studies, all published in 2008. [5] The project pulled these studies from three different journals, Psychological Science, the Journal of Personality and Social Psychology, and the Journal of Experimental Psychology: Learning, Memory, and Cognition, published in 2008 to see if they could get the same ...

  4. Reproducibility - Wikipedia

    en.wikipedia.org/wiki/Reproducibility

    Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.

  5. Replication (statistics) - Wikipedia

    en.wikipedia.org/wiki/Replication_(statistics)

    In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [ 1 ]

  6. Pseudoreplication - Wikipedia

    en.wikipedia.org/wiki/Pseudoreplication

    Sacrificial pseudoreplication (Figure 5b in Hurlbert 1984) occurs when means within a treatment are used in an analysis, and these means are tested over the within unit variance. In Figure 5b, the erroneous F-ratio will have 1 df in the numerator (treatment) mean square and 4 df in the denominator mean square (2-1 = 1 df for each experimental ...

  7. Case study (psychology) - Wikipedia

    en.wikipedia.org/wiki/Case_study_(psychology)

    Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion. [2] Like other research methodologies within psychology, the case study must produce valid and reliable results in order to be useful for the development of future research. Distinct ...

  8. HARKing - Wikipedia

    en.wikipedia.org/wiki/HARKing

    HARKing (hypothesizing after the results are known) is an acronym coined by social psychologist Norbert Kerr [1] that refers to the questionable research practice of "presenting a post hoc hypothesis in the introduction of a research report as if it were an a priori hypothesis".
