Interpolation in Data
Captions available
The idea
Interpolating means estimating a value between two measured points, assuming the trend continues smoothly between them.
In practice
If an invented plant measured 10 centimeters on day 4 and 16 on day 6, it was likely about 13 on day 5.
Where people slip
Interpolation assumes no surprise between points; it is safest when the measured points are close together.
