Replication, which is the reproducing of an existing study. Obtaining similiter results from a repeated study is an essential feature of scientific researches (Zwaan et al. 2018).
Replication determines whether a finding is a single observation or an evidential scientific discovery (Zwaan et al. 2018). It was also pointed out by Zwaan et al. that “a scientific discovery requires both a consistent effect and a comprehensive description of the procedure used to produce that result in the first place.” The report of the research should also have a detailed methodology so that the procedures can be replicated by others. Alarms towards replications have arisen since the research data of a hundred replication experiments have been published in journal Science in 2015. A hundred experiments were done to determine the reproducibility of some of the most well-known experiment.
Statistically significant p values below .05 were reported from 97% of the original studies. However, only 36% of the replication studies found statistically significant results (p < .05) (Open Science Collaboration, 2015).
