magnitude

A logical question following the establishment of an identity and the allocation of a location is the question: What magnitude of the occurrence exists at that location? Is the occurrence large? Small? Voluminous? (p. 32)

To comprehend and measure the amount of a particular feature or phenomenon and to order or classify that phenomenon on the basis of differing magnitudes (p. 95)

Recognize differences in quantity of occurrences (p. 698)

The dimensions, extent, scale, or size of objects or events; also the value (greater or lesser) of a variable obtained from measurements and expressed as a quantity together with a reference to an accepted measurement scale (the units). The units for most physical variables are combinations of mass, length and time (dimensional analysis). The term order of magnitude is applied to a change by a power of ten in a value. Values ranging over many orders of magnitude are frequently expressed in non-linear form such as a logarithmic (or exponential) scale. An emergent property is one that appears as a consequence of large shifts in magnitude.
