Question 60

Replication is used in DOE __________________.

To estimate the error on inherent variation in the process.

To identify the factors.

To set the levels.

To determine whether two factors are interacting or not

Correct Answer: A

Replication is used in Design of Experiments (DOE) to estimate the error or inherent variation in the process. By replicating the experiments, it becomes possible to measure the variability which can be attributed to random variation, thus helping to achieve more accurate and reliable results.

Discussion

InvisibleBeingOption: A

In the context of Design of Experiments (DOE), replicated runs and repeated runs are both multiple response readings taken at the same factor levels. Inherent Process Variation is the portion of Process variation due to Common causes only.
