Understand the concept of 'Replication': Replication in scientific experiments refers to the process of conducting the same experiment multiple times to ensure that the results are consistent and reliable.
Differentiate between the given terms: Standardization, Calibration, Validation, and Replication. Each of these terms has a specific role in scientific experiments.
Standardization involves establishing norms or standards for a procedure or measurement.
Calibration is the process of adjusting and setting a measuring instrument to ensure its accuracy.
Validation is the process of confirming that a method or instrument meets the required specifications and is suitable for its intended purpose.
Identify that 'Replication' is the method that involves performing an experiment multiple times to ensure accuracy in results, as it helps in verifying the consistency and reliability of the findings.
