Extrapolation in Data
Captions available
The idea
Extrapolating means extending a trend beyond the measured range. It is less certain than interpolation, because the trend may change outside the data.
In practice
An invented plant growing 3 centimeters a day reached 18 on day 6, suggesting about 24 on day 8, if growth continues.
Where people slip
An extrapolated answer carries a condition: if the trend continues.
