Post hoc comparisons using the Tukey HSD test are typically conducted to explore the nature of differences between group means when the interaction effect in a two-factor between-subjects ANOVA is statistically significant. This allows for a detailed examination of how the levels of one factor affect outcomes across the levels of another factor.
