  2. Replication crisis - Wikipedia

    en.wikipedia.org/wiki/Replication_crisis

    An investigation of replication rates in psychology in 2012 indicated higher success rates of replication in replication studies when there was author overlap with the original authors of a study [224] (91.7% successful replication rates in studies with author overlap compared to 64.6% successful replication rates without author overlap).

  3. Replication (statistics) - Wikipedia

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

    Example of direct replication and conceptual replication. There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced. [3]

  4. 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 ...

  5. 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.

  6. Research transparency - Wikipedia

    en.wikipedia.org/wiki/Research_transparency

    Replication studies or assessments of replicability aims to re-do one or several original studies. Although the concept has only appeared in the 2010s, replication studies have been existing for decades but were not acknowledged as such. [ 78 ]

  7. External validity - Wikipedia

    en.wikipedia.org/wiki/External_validity

    The ultimate test of an experiment's external validity is replication — conducting the study over again, generally with different subject populations or in different settings. Researchers will often use different methods, to see if they still get the same results. When many studies of one problem are conducted, the results can vary.

  8. Pseudoreplication - Wikipedia

    en.wikipedia.org/wiki/Pseudoreplication

    Hurlbert reported "pseudoreplication" in 48% of the studies he examined, that used inferential statistics. [2] Several studies examining scientific papers published up to 2016 similarly found about half of the papers were suspected of pseudoreplication. [4]

  9. OHBM Replication Award - Wikipedia

    en.wikipedia.org/wiki/OHBM_Replication_Award

    The OHBM Replication Award is an award presented annually by the Organization for Human Brain Mapping (OHBM). It is presented to a researcher in recognition of conducting and disseminating the results of a neuroimaging replication study of exceptional quality and impact.
