Extrapolation
VocabularyExtrapolation applies a model beyond the range of observations used to support it.
Explanation or usage
Extrapolation uses a model or observed pattern to estimate values beyond the range of the data. It depends on assumptions about how the pattern continues; relationships can change or encounter limits. Predictions farther beyond the observed range warrant closer scrutiny of those assumptions.
Common misunderstandings
A fitted line guarantees the same trend indefinitely.
In How Not to Be Wrong

When evaluating a trend projection, distinguish observed data from extrapolated values and consider whether conditions or relationships may change beyond the observed range.
