Question

What is meant by the term replication? What role does it play in DOE

Answer 1

Design of experiments (DOE) is that branch of applied statistics that comprehends with the planning, conduction analysing and interpretating the tests to evaluate and check the factors which control the values of a group of parameters.

Replication is defined as multiple experiments with thr same quality and quantity of factor settings. They are the subject of the same sources of indepentently and variability of each other. Many things can be replicated like the combinatioms, factor levels and designs. It is said that if the results can be replicated, it means they have the tendency of being correct. It is an important part of sciene and statistics which is used to check the reliability of the work. The role of replication plays as if the particular task replicates the same result it means it is being verified and if not, it is not likely to be well accepted.

If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeate many times and the same result is always obtained.
