What is the exact differences between the meaning of the nouns "measure" (w.r.t. measurement, not course of action) and "metric"? Can they be used synonymously? While few dictionaries do not know metric as a noun at all, others are a bit fuzzy about the meaning. In the scientific literature (in my area) they sometimes seem to be used interchangeably. However, quite a lot authors are not native speakers.
Usage examples are,
- "Depending on the objectives, one need different [measures/metrics] for evaluation."
- "Reliability is a [metric/measure] to measure the system's ability to survive."
- "If we use another [measure/metric] we will come up with different results."
