Plackett-Burman designs are very good at determining the factor effects, while the factorial designs
predict the significance of the interaction terms in addition to the factor effects.
In this study, fractional factorial design
was utilized in designing the experiments.
Starting with standard FC-2174 fluoroelastomer gum, levels of Curative A and Curative B were varied in a two level factorial design
to help determine the discriminating power of each Machine-Arc combination.
2] factorial design
supports a first order model with interactions as shown below.
A standard order, eight-run, full factorial design
served as the second experiment (table 6).
According to the trial's 2x2 factorial design
, subjects were randomized to receive ramipril 15 mg vs.
Patients presenting within 24 hours of the onset of symptoms who were hemodynamically stable were randomized, in a 2 x 2 factorial design
, to six weeks of either
In their research, the scientists applied a full factorial design
using three levels of pH--2, 3 and 8--at four concentrations of WPI: 0%, 2.
Design type was defined as custom factorial design
Graft copolymerization of sorbic acid onto polypropylene (PP) film was carried out using full factorial design
A full factorial design
technique was used to study effects of reflow soldering process parameters.
The study, known as the Trial to Assess Chelation Therapy (TACT), had a double-blind, placebo-controlled, 2 x 2 factorial design
, in which patients received 40 intravenous infusions of EDTA, a daily high-potency 28-component multivitamin-multim ineral formula, both treatments, or placebo.
