Replication
This has different definition. It is when a researcher repeats that is replicate research findings through correct use of operational definitions, procedures, etc.
A good research mut be replicated and it must result in the same or similar in terms of findings each time the experiment is performed.
It also implies that the treatment used in an experiment was used more than once in an experiment. It because allows us to estimate the inherent variability in the data. This allows us to know and judge if an observed difference in treatment was as a result that is it could be due to chance variation.
Replication is very important because when we have one experiment or treatments once, we would not know if the observed difference is due to the treatments or just random variability. But replication helps you to know the reason for the observed differences.
