    2021-12-9 · Informal introduction to factorial experimental designs. The purpose of this page is to clarify some concepts, notation, and terminology related to factorial experimental designs, and to compare and contrast factorial experiments to randomized controlled trials (RCTs). A more in-depth introduction can be found in Chapter 3 of Collins (2018).

  • I. Introduction to the Analysis of Factorial Experiments

    2006-12-5 · 8. Factorial designs are quite common in psychology. We discuss only the simplest form of the factorial design, t he two-factor design, but mor e complic ated designs are re port ed in the contemporary research literature. 9. A good grounding in the design and analysis of two-factor experiments will help you understand more complex designs. 10.

    2008-4-9 · Experimental design is an effective tool for maximizing the amount of information gained from a study while minimizing the amount of data to be collected. Factorial experimental designs investigate the effects of many different factors by varying them simultaneously instead of changing only one factor at a time. Factorial designs allow

    The sample size is the product of the numbers of levels of the factors. For example, a factorial experiment with a two-level factor, a three-level factor and a four-level factor has 2 x 3 x 4 = 24 runs. Full factorial designs are often too expensive to run, since the sample size grows exponentially with the number of factors.
