Reproducibility is tested by a replication study, which must be completely independent and generate identical findings known as commensurate results. It is one of the main principles of the scientific method. It must be designed in such a way that anyone else anywhere else can reproduce it and hopefully get the same results. The results are reproducible. It refers to a person reproducing someone else’s experiment. Its important as this helps to show that the experiement is valid and correct, because a number of different people did it and got the same results, and the results werent simply because of some mistake by one person.
