A factorial design is an experimental design in which each level of each independent variable is replicated across all levels of the other independent variables.
A 2×4 independent-groups factorial design is a type of research design that is used to study the effects of two independent variables on a dependent variable. Two independent variables, one with two levels and one with four levels, are used in a 2 x 4 design.
This design is used when there are two or more independent variables that are each manipulated by the researcher. The dependent variable is measured at the end of the experiment.
