Consider a special 8-sided die with 1 face painted 1, 2 faces painted 2, 3 faces pa Posted 4 days ago. In factorial designs, the main effects are referred to using single uppercase letters, e.

An interactive effect, on the other hand, is referred to by a group of letters denoting which factors are interacting to produce the effect, e. Thus, in a 2-factorial experiment, the treatment combinations are: Based on discussions in this link: The magnitude and polarity or direction of the numerical values of main and interaction effects indicate how these effects influence the process output.

A higher absolute value for an effect means that the factor responsible for it affects the output significantly. A negative value means that increasing the level s of the factor s responsible for that effect will decrease the output of the process.

In a 2 2 factorial experiment wherein n replicates were run for each combination treatment, the main and interactive effects of A and B on the output may be mathematically expressed as follows: The analysis of factor effects in the conduct of 2 k factorial experiments requires a lot of number crunching even if only two levels per factor are considered in such experiments , especially if the number of factors being investigated is high.

As discussed earlier, one can easily compute for the numerical values of factor effects if one knows the formulas to use and the output of each replicate for each combination treatment of the factorial experiment.

Unfortunately, the formulas look daunting to people not accustomed to them. There is, however, an easy way to reconstruct these formulas using Yates Order.
