Classification vs Monothetic - What's the difference.
Some observations are offered on the role of prototypes in classification and on the monothetic-polythetic distinction. Findings: Reid's theories, suitably embedded in fallibilism and augmented with a respect for truth, provide a sound ontological and epistemological basis for classification.
Since the microbiological revolution, most infectious diseases have been defined and classified according to an etiologic criterion, i.e. the identification of single, external necessary causes (for example, Mycobacterium for tuberculosis). This.
Details. mona is fully described in chapter 7 of Kaufman and Rousseeuw (1990). It is “monothetic” in the sense that each division is based on a single (well-chosen) variable, whereas most other hierarchical methods (including agnes and diana) are “polythetic”, i.e. they use all variables together. The mona-algorithm constructs a hierarchy of clusterings, starting with one large cluster.

Bacteriol. 85:68-77. 1963.-Previous applications of quantitative methods to bacterial classification haveresulted in polythetic groupingsin whichno organism necessarily has all the features charac-teristic of its group, and no single property is necessarily possessed.

A monothetic classification allocates items into classes according to their values for a single variable, in contrast to polythetic classifications which use many (usually all) variables. There is also a contrast between agglomerative (i.e. lumping) and divisive (i.e. splitting) approaches.
Polythetic schemes use more than one characteristic (variables). For example, classifiying people solely on the basis of their gender is a monthetic classification, but if both gender and handedness (left, right handed) are used the classification is polythetic. The following diagram is based on Figure 6 in Grabmeier and Rudolph (2002).

The process of classification itself may be achieved in two ways: (a) top-down or deductive classification and (b) bottom-up or inductive classification. These two basic approaches are directly related to the two types of groups discussed above, monothetic and polythetic groups, respectively.
A 737-badged Boeing aircraft was first certified for flight by the US Federal Aviation Authority in 1967. The aircraft was 28.6 m long and carried up to 103 passengers; in 2019, the distant descendant of that aircraft model, the 737 MAX-10, was 43.8 m long and carried 230 passengers.
A self-selected sample of 1420 gamers ranging in age from 12 years to 62 years (mean age 23 years) completed an online questionnaire. The results showed that 44.5% of gamers were classified as addicted according to the polythetic format and 3.6% according to the monothetic format. Ordered logistic regression analysis showed that the variable.
Jonathan Z. Smith employs a similar method of study in an essay explor-ing early Judaism. He argues for the abandonment of monothetic definitions of religion and suggests instead a model of polythetic taxonomies.4 That is, Smith abandons “the quest for a single item of discrimination, the sine qua.
