Replication in research is the process of repeating a study or experiment by other researchers, often independently, to determine whether the original findings can be reproduced and are reliable across different settings, samples, or conditions. If a study's results can be consistently replicated by other researchers, it increases confidence in the validity and generalizability of the original findings, strengthening the scientific rigor of the research. Failure to replicate findings can raise questions about the original study's methodology, potential biases, or the robustness of its conclusions.
