**Balanced Complete Factorial Design**, Furthermore the non-linear relationships between the sample size the power and the detectable standardized effect size are interpretable by investigating the diagnostic graphs of the package. A 22 factorial design is a type of experimental design that allows researchers to understand the effects of two independent variables each with two levels on a single dependent variable. Balanced the design is a balanced factorial.

For example factors A and B might be run 10 times for two levels. High and watering frequency daily vs. The following is an example of a full factorial design with 3 factorsthat also illustratesreplicationrandomization andadded center points. In R we would just use the model formula Y Block A B We can test the interaction even if we only have one replicate per combination per block.

### A balanced a bfactorial design is a factorial design for which there are alevels of factor A blevels.

One of the big advantages of factorial designs is that they allow researchers to look for interactions between independent variables. Such a design although both balanced and orthogonal would not be a recommended experimental design because it cannot provide an estimate of experimental error. For example a complete factorial design is both orthogonal and balanced if in fact the model that includes all possible interactions is correct. In factorial design a balanced experiment could also mean that the same factor is being run the same number of times for all levels. In the common usage of symmetrical factorial design the term balanced design means completely balanced as. Unbalanced Designs in Testing.
