WebIf factor A has 3 levels and factor B has 5 then it is a 3 x 5 factorial experiment. 9. 3. Example of a 2x2 factorial An example of an experiment involving two factors is the application of two nitrogen levels, N0 and N1, and two phosphorous levels, P0 and P1 to a crop, with yield (lb/a) as the measured variable. The results are shown here: WebUtilizing Design Expert ® software version 7, a full factorial design (2 2) was created to assess the effect of several factors on nanophytosomal formulation (Stat Ease, Inc., Minneapolis, MN, USA). Four runs were required by the design. Two factors were chosen as independent variables, namely PC amount (X 1) and cholesterol amount (X 2).
