Six food critics each visited and rated four different restaurants. Each critic visited each restaurant on three separate occasions and recorded a score for each visit. Assume that results show that there is an interaction. This would mean that, for example, which restaurant is rated the highest depends on which critic does the rating.

An interaction effect in this context means that the effect of one factor (e.g., the restaurant) on the outcome (e.g., the rating) depends on the level of another factor (e.g., the critic). Therefore, if there is an interaction, it implies that different critics may rate the same restaurants differently, leading to a situation where the highest-rated restaurant could vary depending on the critic.
