Discover what a factorial design is. See an example of a 2x2 factorial research design with main and interaction effects. Learn about the pros of...
Factorial designs are used in experiments where the effects of different factors, or conditions, on experimental results are to be elucidated. Some practical examples where factorial designs are optimal are experiments to determine the effect of pressure and lubricant on the hardness of a tablet ...
The chapter begins providing the definition of the basic terms underlying the factorial design, then, it presents examples from literature applying factorial designs starting with the simpler ones, such as 2. Then, the chapter evolves presenting optimization and response surface methodologies factorial ...

Factorial designsare essentially multifactor designs that are balanced, so that all variable combinations are represented and have equal numbers. All the examples in the two- and three-wayANOVAsin this chapter are balanced in this way and are factorial designs. The kidney-cooling experiment, contain...
Design of experimentsNormal probabilityProbability plotUnreplicated factorial designsSignificance testIn this article, we consider the use of Daniel's normal probability plotting procedure for the analysis of unreplicated factorial designs. In these designs, the lack of a formal experimental error variance...
Two examples taken thereafter can show practically applications of discount coefficient method in the design of complete factorial experiments and fractional factorial experiments respectively. 本文通过介绍在自动调节系统中常用的 TAGUCHI 最优校正法,引入折扣系数的概念;然后论述了在实验数据的方差分析中如何利用折...
Joiner and Campbell (1976) gave some more specific examples as to when trend effects can occur in sequential experiments. Therefore, it is important to consider systematic designs in which the estimat...doi:10.2307/2290148Ching-Shui Cheng

Now you should have a good understanding of how to design and conduct a two-by-two factorial experiment, as well as how to statistically analyze the results common to these studies. You’ve also been introduced to several examples where the use of a two-by-two factorial design is beneficial...
