According to Wen Li (2015), there are different statistical methods available for factor screening, such as one-factor-at-a-time method, Taguchi's method, application of full
factorial experiment design, fractional
factorial experiment design, as well as Plackett-Burman designs.
Therefore many researchers have been made studies on these subjects using various methods such as Taguchi the
factorial experiment design the orthogonal central composite design and response surface methodology.
An experimental work should be conducted involving designing, preparing, and testing various trial mixtures according to the full
factorial experiment design considering the various possible combinations of the levels of the mixture variables within their selected ranges of variation.
A
factorial experiment design was used to evaluate the effects of sucrose, boric acid, and calcium nitrate on sorghum pollen germination.
A multi-factor approach to experimentation was adopted, using
factorial experiment design [refs.
