The results are more reliable for interpolation .
Because of what it does
Interpolation and Extrapolation
Interpolation & extrapolation
Interpolation is filling in the data points between the data that has already been collected. Extrapolation is filling in data points beyond the data that has already been collected, or extending the data.
Extrapolation involves predicting values outside of the range of known data, while interpolation involves estimating values within the known data range. Extrapolation assumes that the pattern observed in existing data continues beyond what is measured, which can lead to more uncertainty compared to interpolation. Interpolation, on the other hand, is used to estimate values between existing data points.
Both, interpolation and extrapolation are used to predict, or estimate, the value of one variable when the value (or values) of other variable (or variables) is known. This is done by extending evaluating the underlying function. For interpolation, the point in question is within the domain of the observed values (there are observations for greater and for smaller values of the variables) wheres for extrapolation the point in question is outside the domain.

If you are predicting a point that's outside of the data range, it is known as extrapolation. If it is within the data range it is interpolation and is much more reliable.
Interpolation or extrapolation upon known scientific facts or principles.
Interpolation is the process of estimating the value of some data and processing it in-line with other data obtained from another source. Extrapolation is the ability to estimate the value of something outside a known range from values within that range by assuming that the unknown quantity follows logically from an analysis of the known ones
Two of the defining traits of Science Fiction are interpolation and extrapolation. Most sf is extrapolation and wild extrapolation at that and has lost much of its impact. So when some subtle interpolation comes along people (sf readers) take notice. It also touches on our own frailty as humans, giving us a new perspective on reality, something that is difficult to do in sf.
