What is the main purpose of a decision tree?

The main purpose of a decision tree is to illustrate possible decision outcomes. This tool visually represents all potential choices and their consequences, allowing decision-makers to map out different paths and explore the implications of each option. By clearly laying out various outcomes and their associated probabilities, a decision tree helps individuals visualize complex decision-making processes, making it easier to assess alternatives and their potential impacts.

This visualization supports logical thinking and can lead to more informed and rational decision-making. It incorporates both the possible decisions that can be made and the various outcomes, including both favorable and unfavorable results, enhancing understanding and aiding in the evaluation of choices.
