Hidden variables may refer to:

  • Hidden variable theories, in physics a class of theories trying to explain away the statistical nature of quantum mechanics
  • Latent variables, in statistics, variables that are inferred from other observed variables
  • Hidden transformation, in computer science, a way to transform a generic constraint satisfaction problem into a binary one by introducing new hidden variables
  • Confounding or hidden variables in general. That is, a variable that actually creates the illusion of a causal relation (e.g. firemen often appear after smoke, not because smoke causes firemen, but because fire causes both smoke and firemen)
