WebIn factorial designs, thus two levels each of factor A and B in a factorial design, the main effects of two factors say A and B be can be calculated. The main effect of A is given by The main effect of B is given by Where n is total number of replicates. We use factor level 1 to denote the low level, and level 2 to denote the high level. WebHere is a basic 2 3 design in standard Yates notation defined by the levels of A, B, and C: We can then construct the levels of D by using the relationship where D = ABC. Therefore, in the first row where all the treatments are minus, D = -1*-1*-1 = -1. In the second row, +1, and so forth. As before we write - and + as a shorthand for -1 and +1.
