How to use extrapolate
Extrapolate is used in scientific, statistical, and analytical contexts to describe reasoning from known data to make predictions or inferences about unknown situations. It carries an implication that the extension may involve risk or uncertainty, unlike more certain deduction. The word assumes continuity of patterns and is often qualified with warnings about reliability.
