The graphical comparison of well-understood data sets, called type curves, to another data set. If a certain type
curve closely corresponds to a data set, then an
interpretation of similarity can be made, although, as Sheriff (1991) points out, there might be other type curves that also match the data of interest. Curve matching differs from curve fitting in that curve fitting involves
theoretical models rather than actual examples.
