population characteristic is something we want to estimate about the population. Common examples of population characteristics are totals and averages for variables. Statisticians often call these characteristics "parameters".

The integral part (whether positive or negative) of a logarithm.

The characteristic n of a ring A is the unique non-negative integer with the property that the collection of integers m for which m1A = 0 in the ring is the set of multiples of n. The characteristic of a field is either a prime number p in which case the field has a smallest subfield isomorphic to Zp, the ring of integers modulo p, or else 0, in which case the field has a smallest subfield isomorphic to Q, the ring of rational numbers.

The characteristic of a ring is the smallest positive integer satisfying 1 = 0 if it exists and 0 otherwise. In particular ne=0 for all elements of the ring.

the integer part (positive or negative) of the representation of a logarithm; in the expression log 643 = 2.808 the characteristic is 2

A physical, chemical, visual, function al or any other identifiable property of a product or material, [D00224] MIL-STD 109A QMPP

a conditional (the if half of a rule) that identifies a subset of the domain that is important for determining what feedback to deliver to the student

an intrinsic or physical property of an agent

a property, which helps to identify, or differentiate between, items within a given lot

One of the basic constituents of reproduced sound, which contributes to its perceived quality. Frequency response, loudness, extension, soundstaging, and resolution are sonic characteristics.

A characteristic is the name of the biological, chemical or physical constituent being investigated. For example, in an analysis for phosphorus, the name of the characteristic is phosphorus.

A special quality or appearance that makes an individual or group different from others.
