We here at AGCS want to be hip. A while back we started using the terms metric and measure specifically: metric - a data item (e.g. widget, hour) measure - a combination of one or more metrics that reflects the attributes of an entity (e.g. widgets per hour) We recently had an interchange with another company and they used these terms exactly the opposite. As I said in my intro, we here at AGCS want to be hip - we want to use these terms as they are known in the industry. Does anyone know of an IEEE or ACM definition of these terms: metrics and measure? -- Scott Sheppard UUCP: ...!ncar!noao!asuvax!gtephx!sheppards

For example, length is a metric for quantifying the physical size of an object. In your example above, widget is not a metric but hour is (a metric of duration). A set of metrics which identifies all attributes of interest of an item is said to completely define the item. When you have obtained values for each metric of the set, you have completely described the item. Some people use the term measure (as in, to have the measure of an item) to indicate that they have completely described the item. I do not know if this is a standard usage of the term. -- Blessed Be, Jeff Hull ...!ncar!dinl!hull 1544 S.

(For example, a formula to compute a distance between points in an abstract mathematical space.) To "measure" is to apply the standard. So it's a little circular... You get the idea. A "measure" is a portion. The result of measuring is a "measurement", although you will hear the word "measure" used to mean "measurement". A distance metric is supposed to have the "triangle property", which says that if you add up distances along a connected path, you never get less than the distance between the ends of the path. Now a word of warning. The dictionary does not always do the trick because computer jargon gets it all mucked up. For example, look up "synchronous" and you'll find that it means exactly the opposite of its meaning in software jargon. And the dictionary definition of "paradigm" (last year's most popular buzz-word) bears no resemblance to what the dictionary says it means. But I still recommend the dictionary, because it also makes an excellent bookend or paperweight. ... Now let's play computer Jeopardy ... I'll take computer jargon for $200. The answer is, "in the jargon of computer testing, it means to measure a voltage over a very brief period of time." "Strobe, er... I mean, What is strobe?"

In analysis, a measure is an assignment of a number to each measurable set (whatever that is.) Doesn't that make it a standard of measurement? Or, for another example, isn't a quart measure (don't sit on it) used to measure volume (in quarts?) doesn't that make it a standard of measure? Peace, Bill White P.S. Hi, Dave
