extrapolate
Significado: To extend the application of known information or data to an unknown situation; to estimate or project beyond the range of available evidence.
In statistics and mathematics, extrapolation involves extending a trend or pattern beyond the observed data range to make predictions. More broadly, it means drawing wider conclusions from specific examples. The word carries an inherent caution — extrapolating too far from limited data can lead to unreliable conclusions.
