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
