Definition
Reproducibility, replicability and repeatability are related terms used differently by different research communities to refer alternately to: a) the ability to re-run analyses or computational methods and get consistent or identical results (sometimes called computational reproducibility) or b) the ability to re-run a study's methodology and get consistent results from running a new study by following procedures as closely as possible (sometimes called experimental replicability). In general, reproducibility, replicability and repeatability can be assumed to mean something relating to re-running an experiment and getting consistent or identical results.
