How do text-based descriptive data relate to numeric-value analytical data?
• The values of grain size, percent gravel, carbonate, and other factors that are calculated from text-based data are based on fuzzy set theory calculations. They are memberships, reduced to a single value. An analysis is also a single realized value of the fuzzy set. • Sometimes text-based and numeric-value results are available for the same sample, which allows for an intercalibration of the two forms of output.
