The decision tree is the basis of the PC-ORD Advisor Wizard.   It's purpose is to help you to decide how to analyze your ecological community data.  The tree deals only with relatively common data analysis problems that you are likely to encounter with community data.  The decision tree node numbers correspond to Wizard node numbers so you can follow along the logic.  Note that the logic behind each decision point is available with a click if you work through the tree in the software.
