What is a figure legend used for on a graph?

A figure legend on a graph serves to identify target behaviors and interventions, which is crucial for interpreting the data presented. It provides essential information about what each symbol, color, or line on the graph represents, allowing viewers to understand the specific aspects of the data that relate to the interventions being used. This clarity helps stakeholders, such as practitioners and parents, to quickly grasp the key elements being depicted in the graph, making it easier to analyze the effectiveness of the interventions for the target behaviors.

While other options may have their own significance, they do not capture the primary function of a figure legend. Aesthetic value can enhance the overall presentation of a graph but is not the core purpose of a figure legend. Representing statistical data might be part of what the graph does, but it does not specifically address the identification of behaviors and interventions. Summarizing the analysis pertains more to discussion and interpretation rather than the direct identification feature that a figure legend provides. Overall, the correct choice emphasizes the informative role of the figure legend in connecting the visual data to the specific behaviors and interventions being targeted.
