One way to detect fraud in research is to replicate the study. Replication involves carrying out a similar study under similar experimental conditions. Replication of study is useful for some reasons which include; a test of validity or reliability of the previous results, determination of generalizability or the role of extraneous variables among others. When a study is replicated and the results are similar to those obtained in the previous study, such result can be termed reliable and valid. However, if on several replications, the obtained results differs from those of the initial study, it is an indication of fraud.
