numerical measure of performance
A number or measure that shows how well something is working or how much progress has been made.
用法パターン：
a metric for [doing something]
よくある間違い：
Learners sometimes think 'metric' only means the metric system of units. In modern business and technology, 'metrics' very often means performance measures, like sales numbers, response times, or error rates. Also, learners may say *'many metric'* instead of the correct plural *'many metrics'*. Use 'metric' for one measure and 'metrics' for several.
類義語
measure (More general; can be numerical or not, and less tied to business or data analysis contexts.)
|
indicator (Focuses on something that shows a result or state, not always strictly numerical.)
対義語
guess (Emphasizes a judgment made without clear numbers or standards, the opposite of using defined metrics.)

よくある間違い：
Learners sometimes confuse 'metric' with 'meter.' 'Metric' describes the whole system (metric units, metric system), while 'meter' is one unit in that system. Also, 'metric system' is standard; phrases like *'meter system'* are incorrect.
類義語

対義語

mathematical distance function
In higher mathematics, a special rule that gives a distance between any two points in a set and follows fixed rules.
用法パターン：
define a metric on [a set]
よくある間違い：
Learners may confuse the general English sense of 'metric' (a performance measure) with the strict mathematical definition. In mathematics, a metric must satisfy specific axioms such as symmetry and the triangle inequality; not every kind of 'measurement' is a metric in this technical sense.
類義語
distance function (A more descriptive phrase, often used informally to explain what a metric does.)
対義語
non-metric (Used in mathematics to describe a structure or space that does not satisfy the axioms of a metric.)

relating to poetic meter
About the beat or rhythm pattern in a poem.
