In experimental research, the switching replication design can address frequent issues.

Second, the switching replication has the potential to increase external validity by highlighting the consistency of treatment effects by utilizing numerous separate administrations of the medication. The researcher can increase statistical power in situations when the treatment is not anticipated to have a long-lasting impact by combining the treatment and control groups across treatment administrations.
