Definition

Noun: A deliberately introduced margin of error, adjustment, or allowance, often used to make results appear more accurate, acceptable, or to account for uncertainty. It is typically an arbitrary figure added to or subtracted from calculations or data.

Usage

The term "fudge factor" is used to describe an unofficial, often subjective, adjustment made to data, a formula, or a plan. It implies a degree of imprecision or manipulation, sometimes to achieve a desired outcome or to simplify a complex reality. * The engineer included a fudge factor in the budget to cover unexpected material costs. * Their model's predictions were off, so they applied a fudge factor to align it with the observed results.

Advanced Usage

  • The constant in the equation isn't derived from first principles; it's essentially a fudge factor to make the theory fit the data.
• In Business and Planning: An extra amount of time, money, or resources added to an estimate to create a safety buffer.
