Fractional Factorial designs for an experimental approach are used when ____________ about the multiple metric interaction in a process.
Fractional Factorial designs for an experimental approach are used when ____________ about the multiple metric interaction in a process.
Fractional Factorial designs are used when little is known about the multiple metric interactions in a process. These designs allow experimenters to investigate the most important factors with a reduced number of experiments, making it efficient and cost-effective when there is uncertainty about the interactions.
B. Little is known
