scale

 [skāl]
1. a thin flake or compacted platelike body, as of cornified epithelial cells. See also squama.
2. a scheme or device by which some property may be measured (as hardness, weight, linear dimension).
3. to remove incrustations or other material from a surface, as from the enamel of teeth.
absolute scale (absolute temperature scale)
1. one with its zero at absolute zero (−273.15°C, −459.67°F).
ASIA scale a descriptive tool developed by the American Spinal Injury Association (ASIA) as a part of the complete classification of patients with spinal cord injuries. Called also Frankel Classification. See accompanying table.
Bayley S's of Infant Development a psychological test for assessing development of infants, using motor, mental, and behavioral developmental scales.
Borg scale a numerical scale for assessing dyspnea, from 0 representing no dyspnea to 10 as maximal dyspnea.
Brazelton Neonatal Behavioral Assessment scale a behavioral assessment scale used to evaluate the interactive behavior of a newborn by its responses to environmental stimuli.
Celsius scale (C) a temperature scale with zero at the freezing point of water and the normal boiling point of water at 100 degrees. The abbreviation 100°C should be read “one hundred degrees Celsius.” (For equivalents of Celsius and Fahrenheit temperatures, see Appendix.)
centigrade scale one with 100 gradations or steps between two fixed points, as the Celsius scale.
Fahrenheit scale (F) a temperature scale with the freezing point of water at 32 degrees and the normal boiling point of water at 212 degrees. The abbreviation 100°F should be read “one hundred degrees Fahrenheit.” (For equivalents of Fahrenheit and Celsius temperatures, see Appendix.)
French scale one used for denoting the size of catheters, sounds, and other tubular instruments, each French unit (symbol F) being approximately 0.33 mm in diameter.
Glasgow Coma scale a standardized system for assessing response to stimuli in a neurologically impaired patient, assessing eye opening, verbal response, and motor ability. Reaction scores are depicted in numerical values, thus minimizing the problem of ambiguous and vague terms to describe the patient's neurologic status. (See accompanying Table.) The total score is obtained by adding E, M, and V; a score of 7 or less indicates coma and a score of 9 or more rules out coma.
Global Assessment of Functioning (GAF) scale a hundred-point scale used as axis V of DSM-IV to assess a client's recent and current levels of social, psychological, and occupational functioning.
gray scale a representation of intensities in shades of gray, as in gray-scale ultrasonography.
interval scale a scale having equal numerical distances between intervals in addition to mutually exclusive categories, exhaustive categories, and rank ordering but no zero point.
Karnofsky scale (Karnofsky performance scale) a widely used performance scale, assigning scores ranging from 0 for a nonfunctional or dead patient to 100 for one with completely normal functioning.
Kelvin scale an absolute scale in which the unit of measurement, the kelvin, corresponds to that of the Celsius scale; therefore the ice point is at 273.15 kelvins.
Likert scale a tool used to determine opinions or attitudes; it contains a list of declarative statements, each followed by a scale on which the subject is to indicate degrees of intensity of a given feeling.
Neonatal Behavior Assessment scale Brazelton Neonatal Behavioral Assessment Scale.
performance scale a scale that measures a patient's performance status, serving as a prognostic indicator of seriousness of disease or disability. The most widely used scale is the Karnofsky scale.
Problem Rating scale for Outcomes see problem rating scale for outcomes.
semantic differential scale a measurement device that consists of two opposite adjectives with a seven-point scale between them; each item under examination is assigned to a specific point on the scale.
temperature scale one for expressing degree of heat, based on absolute zero as a reference point, or with a certain value arbitrarily assigned to such temperatures as the ice point and boiling point of water.

in·ter·val scale

like a temperature scale in Celsius or Fahrenheit units, a scale on which the intervals are equal but which has an arbitrary zero point; for example, intelligence quotient values are values along an interval scale.

A number of researchers in the organizational sciences have identified several issues of level of theory, level of measurement and level of analysis.
Level of measurement refers to the unit to which the data are directly attached, whereas level of analysis is the unit to which the data are assigned for hypothetical testing and statistical analysis (Rousseau, 1985).
Frequently in organizational research there is theory to support both level of measurement and level of analysis at the individual, group, and/or organizational level.
The mode or the score or measurement that occurs most frequently is the only measure that is appropriate for data at the nominal level of measurement.
Which statistics to use depends on several considerations, including the purpose(s) of the study, number and type(s) of variables, level of measurement, method of selecting the sample, the distribution of the variables of interest, and the number of groups involved.
In addition to the purpose(s) and the number and type of variables, a third consideration is the scale or level of measurement used to measure the variables.
The fact that such small devices can withstand harsh conditions such as moisture and dust while providing a high level of measurement accuracy will further necessitate their role in environments where dimensional reliability is crucial.
The Agilent PNA Series is an entirely new family of instruments designed to exploit state-of-the-art technologies and delivers the highest level of measurement performance ever manufactured by Agilent or its predecessor, Hewlett-Packard, a distinction held previously by the Agilent 8753 family, introduced in 1986.
I've taken more than 20 years of personal experience in the physician practice management field and created this tool that provides a similar level of measurement, feedback and guidance that one might get from a consultant, for a fraction of the cost," he added.
The Viper system provides a level of measurement accuracy not available on other systems in the same price range.
The 5500 Series is the second generation of production tools designed specifically for FPD applications, and incorporates a level of measurement sophistication, ease of operation and substrate handling capability which meets the current and future demands of leading edge display manufacturers.
We have designed the NanoSpec 8000 to provide our customers with high throughput at a high level of measurement precision, quality and safety.
