TREE DIAGRAM

The term 'tree diagram' is used in different ways in different disciplines.

★ In mathematics and statistical methods, a tree diagram is used to determine the probability of getting specific results where the possibilities are nested.

★ In physics, a 'tree diagram' is an acyclic connected Feynman diagram. The word tree is used just as in graph theory. A tree diagram corresponds to the results obtained from classical physics . One does not need to perform any integrals to calculate a tree diagram. The full result for the physical quantity must however include one-loop Feynman diagrams and also more complicated diagrams.

★ In linguistics, a 'tree diagram' or parse tree is one way to visually represent the structure of a sentence (see ''X-bar theory''), a syllable, or phonological feature geometry.
