Example of an experiment: The experiment investigates the understandability of the design document when using structured or object-oriented design based on one ‘good’ and one ‘bad’ requirements documents. The first factor, A, is the design method and the second factor, B, is the requirements document. The experiment design is a 2*2 factorial design as both factors have two treatments and every combination of the treatments are possible.
