numerical taxonomy The classification of organisms by purely mathematical means. It is based on quantifying observable characteristics of organisms and may be operated at various taxonomic levels to deal with species or higher taxa. It involves the grouping and computation of the similarity of characters; the results are usually displayed graphically, as a phenogram or dendrogram. There has been discussion as to whether classifications produced in this way are valid and reflect phylogeny. See TAXON; and TAXONOMY.
