There is some confusion in the literature on the meaning of the term reproducibility. We follow an interpretation that is consistent with NIST, 6 Sigma, ACM, FASEB, The Physiome Project, and Wikipedia. The following definition is taken from the ACM web site:

“The measurement can be obtained with stated precision by a different team, a different measuring system, in a different location on multiple trials. For computational experiments, this means that an independent group can obtain the same result using artifacts which they develop completely independently.”

We distinguish reproducibility from the less stringent repeatability using the following definition of repeatability (again taken from the ACM web site):

“The measurement can be obtained with stated precision by the same team using the same measurement procedure, the same measuring system, under the same operating conditions, in the same location on multiple trials. For computational experiments, this means that a researcher can reliably repeat her own computation.”

To summarise:

Repeatability: Same team, same experimental setup

Reproducibility: Different team, different experimental setup
