Noun

• (applied sciences) the science, and associated technology, of the automatic recording and transmission of data from a remote source to a receiving station for analysis

Adjective

• Of or relating to the metric system of measurement.
• (music) Of or relating to the meter of a piece of music.
• (mathematics, physics) Of or relating to distance.

Noun

• A measure for something; a means of deriving a quantitative measurement or approximation for otherwise qualitative phenomena (especially used in engineering).
• (mathematics) A function for the measurement of the “distance” between two points in some metric space: it is a real-valued function d(x,y) between points x and y satisfying the following properties: (1) “non-negativity”:

  d
  (
  x
  ,
  y
  )
  ≥
  0

  {displaystyle d(x,y)geq 0}
  , (2) “identity of indiscernibles”:

  d
  (
  x
  ,
  y
  )
  =
  0

   iff 

  x
  =
  y

  {displaystyle d(x,y)=0{mbox{ iff }}x=y}
  , (2) “symmetry”:

  d
  (
  x
  ,
  y
  )
  =
  d
  (
  y
  ,
  x
  )

  {displaystyle d(x,y)=d(y,x)}
  , and (3) “triangle inequality”:

  d
  (
  x
  ,
  y
  )
  ≤
  d
  (
  x
  ,
  z
  )
  +
  d
  (
  z
  ,
  y
  )

  {displaystyle d(x,y)leq d(x,z)+d(z,y)}
  .

• (mathematics) A metric tensor.
• Abbreviation of metric system.

Synonyms

• measure
• (mathematics): distance function

Hyponyms

• (mathematics): Euclidean metric, Hausdorff metric, spacetime metric, uniform metric, ultrametric

Examples

• As for the large number of official statements that Spain is safe, I think they are merely a metric of the complacency that has characterised the European crisis from the start.
• Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product , is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.
• What metric should be used for performance evaluation?
• What are the most important metrics to track for your business?
• It’s the most important single metric that quantifies the predictive performance.
• How to measure marketing? Use these key metrics for measuring marketing effectiveness.
• There is a lack of standard metrics.
• As we shall see, these metrics are constructed from a Green function.

Verb

• (transitive, aerospace, systems engineering) To measure or analyse statistical data concerning the quality or effectiveness of a process.

Examples

• We need to metric the status of software documentation.
• We need to metric the verification of requirements.
• We need to metric the system failures.
• The project manager is metricking the closure of the action items.
• Customer satisfaction was metricked by the marketing department.
