Accurate: the nearness of the measure to the ‘true’ value.

Length: the measure from crown of the head [the superior point] to the bottom of the feet with the subject lying horizontally in a supine position. Length is always measured recumbent.

NHANES: the National Health and Examination Survey. The Surveys [NHANES I, II, and III] were conducted by the National Center for Health Statistics [NCHS] from 1963 to 1994.

Reliable: how close repeated measures are to each other.

Stature: the maximum height of an individual. The CDC Growth Charts use the term stature. Stature or height is defined as the measure from crown of the head [the superior point] to bottom of feet. It is always measured standing.

Tare: to set the weight of the scale at ‘zero’ when a weight (person) is on the scale. Another person, in this case, the infant, can then be added and the weight of the infant read directly from the scale.

Tolerance of measures: numerical difference between measures that is still accurate.

Trained measurer: one who has received instruction or certification from another measurer experienced in the proper procedures for body measurements.
