Question

Quizplus · Accepted Answer

The design shown is a 2 x 2 factorial experiment, indicated by the two factors (X11, X12, X21, X22) each at two levels, arranged in a matrix form. This setup allows for the examination of the effects of each factor independently as well as their interaction effect.
