    • n variance In physical chemistry, that property of a chemical system which is expressed by the equation V = c + 2 — φ, where V is the variance, c the number of independent components, and φ the number of phases in which the system may exist. Systems are said to be invariant, univariant, bivariant, multivariant, etc., according to the value of V.
    • n variance The state of being or the act of becoming variant; alteration; variation; change; difference.
    • n variance In law, a discrepancy: Between pleadings and proof, as where a complaint mentions a wrong date, or the facts prove to be different from what was alleged.
    • n variance Between the form of the writ or process by which the action was commenced and the form of the declaration or complaint. Formerly, when variances were deemed more important than now, variance was often defined as a fatal discrepancy or disagreement, etc.; but in civil cases such variances between pleading and proof as do not actually mislead the adverse party are now disregarded as immaterial, and many others are amendable. Under what is known in the United States as the Code Practice, vari ance is used to designate a discrepancy in some particulars only, and is amendable if it has not misled, while a failure of proof as to the entire scope and meaning of an allegation is not regarded as a mere variance, but fatal.
    • n variance Difference that produces disagreement or controversy; dispute; dissension; discord.
    • n variance Variableness; inconstancy.
    • n variance In a state of controversy or dissension; in a state of opposition or enmity.
