INTERPOLATION AND EXTRAPOLATION
The important information in this chapter is summarized below.
Interpolation and Extrapolation Summary
Interpolation Interpolation is the process of obtaining a value from a graph or table that
is located between major points given, or between data points plotted. A
ratio process is usually used to obtain the value.
Extrapolation Extrapolation is the process of obtaining a value from a chart or graph
that extends beyond the given data. The "trend" of the data is extended
past the last point given and an estimate made of the value.
