Decision Tree

A diagram, chart or model which helps support the of decision making, providing a sequence of actions and outcomes, including the likelihood of each option and value of the resultant outcome. Decision trees will typically follow an IF and THEN pattern: IF this is selected THEN this will most likely occur. It can, however, also incorporate other features such as conditional probabilities, whereby the probability of an outcome occurring is dependent or conditional on another event having occurred or being present. For example, the likelihood of a football match being cancelled due to waterlogging, is conditional on, for example, significant features such as the type of pitch construction, the current soil condition (e.g. degree of compaction), recent rainfall figures an forecast figures for the day of play as well as preceding day ¯ along with other features.
