Decision tree

A decision tree is like a flow chart that helps you to make a decision. You start at the top of the tree, and then you answer a question or make a choice. Depending on what you decide, the tree branches out in a different direction that leads to more questions. Each question or choice you make will lead you down a different branch until you come to the bottom of the tree and reach a decision.
