The distribution of elevations representing a region can be shown as a cumulative frequency curve plotted on probability paper. Many elevation distributions are "zig-zag" curves which can be represented conveniently by measures of skewness and kurtosis. A plot of skewness versus kurtosis permits the recognition of six major, non-Gaussian forms, with countless gradations.
