Factorial designs would enable an experimenter to study the joint effect of the factors (or process/design parameters) on a response. A factorial design can be either full or fractional factorial. This chapter is primarily focused on full factorial designs at 2levels only. Factors at 3levels are beyond the scope of this book.

A factorial design contains two or more independent variables and one dependent variable. The independent variables, often called factors, must be for these variables are often called levels. The dependent variable must be continuous, measured on either an interval or a ratio scale.

History. Factorial designs were used in the 19th century by John Bennet Lawes and Joseph Henry Gilbert of the Rothamsted Experimental Station.. Ronald Fisher argued in 1926 that "complex" designs (such as factorial designs) were more efficient than studying one factor at a time. Fisher wrote, "No aphorism is more frequently repeated in connection with field trials, than that we must ask Nature

Jiju Antony, in Design of Experiments for Engineers and Scientists (Second Edition), 2014. Experimenters utilise fractional factorial designs to study the most important factors or process/design parameters that influence critical quality characteristics. Pilot studies, screening experiments, etc. constitute a few of the many settings in which factional fractional experiments are commonly used.

Factorial design studies are named for the number of levels of the factors. A study with two factors that each have two levels, for example, is called a 2x2 factorial design. Learning Outcome

Many Taguchi designs are based on Factorial designs (2level designs and Plackett Burman designs, as well as factorial designs with more than 2 levels). Taguchi''s L8 design, for example, is actually a standard 2 3 (8run) factorial design. Taguchi''s designs are usually highly fractionated, which makes them very attractive to practitioners.

· In this paper, we present one of the first uses of fractional factorial designs in the area of virology by sequentially using two and threelevel fractional factorial designs to investigate a biological system with Herpes simplex virus type 1 (HSV1) and six antiviral drugs: Interferonalpha (A), Interferonbeta (B), Interferongamma (C), Ribavirin (D), Acyclovir (E), and TNFalpha (F).

Regardless, factorial design is a useful method to design experiments in both laboratory and industrial settings. Factorial design tests all possible conditions. Because factorial design can lead to a large number of trials, which can become expensive and timeconsuming, factorial design is best used for a small number of variables with few states (1 to 3).

Screening designs, such as 2k factorial and Doptimal designs, are used to determine critical process parameters. Response surface designs, such as Central Composite Designs (CCDs) and Ioptimal designs, are used to model the functional relationship between those critical process parameters and the critical quality attributes.

The given data is just 16 responses, but for a 4 x 4 x 4 Factorial design the big N (or total sample size) should be 64. If I were to consider the 2way and the 3way interaction effects for this problem, I would have 63 degrees of freedom (df) for my Total Sum of Squares (SSTotal), and as it would turn out, I would have 0 df for my SSError, but I would have covered for the SS of all the effects.

Factorial designs are most efficient for this type of experiment. • In a factorial design, all possible combinations of the levels of the factors are investigated in each replication. • If there are a levels of factor A, and b levels of factor B, then each replicate contains all ab treatment combinations.
