An example of a factorial design is if a researcher wants to evaluate two groups, high school boys and high school girls, and how the effects of mindfulness impact standardized test scores. In this case, the two factors are high school boys and girls. There are also two levels, those who practice mindfulness and those who do not. Thus, this would be written as 2x2, where the first factor has two levels; high school boys/girls, and the second has two levels, mindfulness/no mindfulness. This is a clear example of a factorial design. A benefit of a factorial design is that we can see if there is an interaction between two factors on the DV. What might the interaction between gender and mindfulness on test scores look like?
