WebStatistics 514: 2 k Factorial Design Analyzing 2 2 Experiment Using Regresson Model Because every effect in 2 2 design, or its sum of squares, has one degree of freedom, it can be equivalently represented by a numerical variable, and regression analysis can be directly used to analyze the data. The original factors are not necessasrily continuous. Webdesign, i.e., factorial treatment structure: 1 When interaction is present. 2 When interaction is absent. If interaction is present, a factorial will allow you to study, estimate, and test it. When interaction is absent, a factorial is more e cient than two designs that study A and B separately.

When a design is denoted a 2 factorial, this identifies the number of factors (3); how many levels each factor has (2); and how many experimental conditions there are in the design (2 = 8). Similarly, a 2 design has five factors, each with … See more In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or "levels", and whose experimental units take on all possible combinations of … See more Many people examine the effect of only a single factor or variable. Compared to such one-factor-at-a-time (OFAT) experiments, factorial experiments offer several advantages See more For more than two factors, a 2 factorial experiment can usually be recursively designed from a 2 factorial experiment by replicating the 2 experiment, assigning the first replicate to the … See more In certain symmetric factorial experiments the sets $${\displaystyle U_{I}}$$ that represent interactions can themselves be decomposed orthogonally. A key application is described at the end of this section. Consider the … See more 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 … See more The simplest factorial experiment contains two levels for each of two factors. Suppose an engineer wishes to study the total power used by … See more A fundamental concept in experimental design is the contrast.
