Data replication matters to an underpowered study, but replicated hypothesis corroboration counts

  • Erich H. Witte (a1) and Frank Zenker (a2)


Before replication becomes mainstream, the potential for generating theoretical knowledge better be clear. Replicating statistically significant nonrandom data shows that an original study made a discovery; replicating a specified theoretical effect shows that an original study corroborated a theory. Yet only in the latter case is replication a necessary, sound, and worthwhile strategy.
