Replication

Explanation:

Replication is the principle of research methodology. In research, the term replication means to repeat the research to find out the result. This principle is applied because of findings of the original study can be replicated on other populations or not.

In this research, the researcher used a different situation, different populations to replicate his study. If the study conducted the main interest of the researcher is just to know whether the study result applies to other populations or not.

Replication is very important for research because if replication conducted and the study reveals the same result as the original study was done, it increases the validity of the research. It means that the result can be generalized at all the population.
