In a decision tree, what does a node represent?

In a decision tree, a node specifically represents a choice point in the decision process. This is where different paths diverge based on decisions made or outcomes that could occur. Each decision node indicates a situation where a decision needs to be made, leading to various possible outcomes or subsequent nodes based on the choices available.

Understanding the role of nodes in a decision tree is crucial for visualizing how decisions and their consequences interact over time. The tree structure allows for clarity in seeing how each decision influences subsequent choices and outcomes, making it a valuable tool in decision-making and modeling processes.

The other options describe components or characteristics associated with decision trees but do not accurately define what a node represents within this context. For instance, while one could consider that all possible outcomes stem from these decision nodes, the direct definition of a node itself is not about the outcomes but rather where choices are made.
