This is distinct from retesting a claim using the same analyses and same data (usually referred to as reproducibility or computational reproducibility) and using the same data with different analyses (usually referred to as robustness). Fig 1s right panel illustrates a maturing understanding of the claim. To confirm results or hypotheses by a repetition procedure is at the basis of any scientific conception. The key is to find something that works for you and that you can commit to doing on a regular basis. Replication can occur in observational research when the conditions presumed essential for observing the evidence recur, such as when a new seismic event has the characteristics deemed necessary and sufficient to observe an outcome predicted by a prior theory or when a new method for reassessing a fossil offers an independent test of existing claims about that fossil.

However, as a theoretical commitment, replication does imply precommitment to taking all outcomes seriously. Therefore, declaring that a study is a replication is a theoretical commitment. Learn more about Minitab Statistical Software. Instead, we should perform the test over and over. As with repetition, the most important things to watch for are results that don't fit our hypothesis, and for the same reason. Credibility of scientific claims is established with evidence for their replicability using new data.
