What Are Design Factors?

Factor design means that on the premise of increasing the level of change of one independent variable, we can also expand the design of two 16 groups to examine the effects of multiple variables (factors) in one experiment. In human factors research, we are often interested in complex systems. This often involves the question of the relationship between more than two variables. For example, in the above example of shift work, we may need to know whether the shift arrangement (factor A) has a consistent or different effect on people of different ages (older and younger, that is, factor B). A multifactorial experimental design with several independent variables consisting of several levels is called factorial design. ^[1]
