Abstract
Structural branching of graphs has been investigated extensively. Yet, no method/model has yet been developed which captures all aspects of branching meaningfully. Another shortcoming of nearly all related work in this area is the fact that only small sets of example graphs have been used to perform those studies. Instead, we investigate structural branching of graphs statistically by using large sets of exhaustively generated graphs. Our findings explain some of the limits of existing branching measures as well as the search for novel branching measures by using correlation analysis.

Notes
The star graph is the tree of order \(N\) with \(N-1\) vertices of degree \(1\). The path graph is the tree of order \(N\) without vertices of a degree greater than \(2\).
