Circled decision nodes in a decision tree represent the required decisions an individual or organization must make as they navigate through a set of choices. These nodes are crucial as they highlight points where action is necessary, guiding the decision-maker through various pathways based on their current situation and desired outcome. In a decision tree, each branch stemming from these decision nodes leads to different possible outcomes or scenarios, showcasing the potential consequences of each choice. This visualization helps in analyzing the implications of decisions and considering the best strategic path forward while weighing the risks and rewards associated with each option.
