extrapolation
Extending beyond data
Extrapolation is the act of extending known data or experience into unknown territory—projecting a trend, estimating beyond measured values, or inferring what might be true based on what is known.
Based on current growth, extrapolation suggests the population will double by 2050.
The term appears in statistics, science, and everyday reasoning.
Unlike interpolation, which estimates between known points, extrapolation ventures beyond them, making it inherently riskier.
