Categories Microbiologists do not seem to utilize (full of fractional) factorial experiments very often. It seems like a very convenient way to test combinatorial effects of several factors at once.

advantages and disadvantages of experiments that involve single and multiple factors (i.e., factorial designs). Following these guidelines, you should identify at least two In some cases, experimental design in studies of humans can objectify the research subjects and, at its extreme, dehumanize them. Whether attempting to preserve the natural, observable activities of a population or preserving their self-possession and dignity with a non-invasive approach, non-experimental design works quite well.
