The Answer is A between-subjects factorial design is a research design in which participants are assigned to different levels of two or more independent variables. Each participant is only exposed to one level of each independent variable, and their responses are compared across the different levels of the independent variables.

For example, let's say a researcher is interested in studying the effects of both gender and age on memory performance. They might conduct a between-subjects factorial design study in which participants are randomly assigned to one of four groups: male/young, male/old, female/young, and female/old. Each group represents a combination of the two independent variables (gender and age), and the researcher can then compare memory performance across the four groups to see if there are any significant differences.

In this example, the between-subjects factorial design allows the researcher to examine the main effects of gender and age, as well as any potential interactions between the two variables, on memory performance. This design is useful for studying the effects of multiple independent variables on a dependent variable, and it helps to control for individual differences by assigning different participants to each level of the independent variables.
