From Repeatability to Reproducibility and Corroboration

Abstract

Being able to repeat experiments is considered a hallmark of the scientific method, used to confirm or refute hypotheses and previously obtained results. But this can take many forms, from precise repetition using the original experimental artifacts, to conceptual reproduction of the main experimental idea using new artifacts. Furthermore, the conclusions from previous work can also be corroborated using a different experimental methodology altogether. In order to promote a better understanding and use of such methodologies we propose precise definitions for different terms, and suggest when and why each should be used.
