Binary decision information


A binary decision is a choice between two alternatives, for instance between taking some specific action or not taking it.[1]

Binary decisions are basic to many fields. Examples include:

  • Truth values in mathematical logic, and the corresponding Boolean data type in computer science, representing a value which may be chosen to be either true or false.[2]
  • Conditional statements (if-then or if-then-else) in computer science, binary decisions about which piece of code to execute next.[3]
  • Decision trees and binary decision diagrams, representations for sequences of binary decisions.[4]
  • Binary choice, a statistical model for the outcome of a binary decision.[5]
