- A straight-line estimation method where the estimated result lies beyond the range spanned by two or more known data points.
- More generally, any estimation method where the estimated result lies beyond the range spanned by two or more known data points. (Not necessarily using straight-line methods of estimation.)
- Extrapolation is generally a less reliable estimation method than Interpolation.
- Extrapolation can be particularly unreliable when historical trends - for example historic growth rates - are projected into future periods for planning purposes.
