Scenario Researchers Provided Both Content Of Class And Gender Of Ins
Scenario: Researchers provided both content of class and gender of instructor within vignettes for 2 classes of students that were manipulated by the experimenter. For example, the content manipulated in the two different classes was either counseling or research methods. The gender of the instructor manipulated in the vignettes was either male or female. In the research results, the main effects indicated instructor gender and course content were not statistically significant.

Paper For Above instruction
The research design employed in the described scenario is a 2 x 2 factorial design. This design involves two independent variables (IVs)—in this case, course content and instructor gender—each with two levels: counseling vs. research methods, and male vs. female. Participants are exposed to all combinations of these levels, which allows researchers to examine both main effects and interaction effects.
A factorial design is characterized by the manipulation of two or more independent variables simultaneously, enabling the assessment of their individual and combined effects (Creswell, 2014). The strength of a 2 x 2 factorial design lies in its efficiency and ability to explore interaction effects between variables, which can reveal complex relationships that simpler designs may overlook. For example, in a study examining the impact of instructor gender and course content on student engagement, researchers can determine if the effect of instructor gender differs depending on course content (Hulley et al., 2013).
This design’s flexibility makes it ideal for investigating multiple factors within a single experiment, providing comprehensive insights into how variables interplay to influence outcomes. The absence of significant main effects in this experiment suggests that neither instructor gender nor course content independently influenced student perceptions, but potential interactions might still exist—an aspect effectively examined through the factorial design.
