I want a word that means "Selected from the pool/set" - randomness is implied but not necessary. What is a good word for this?

It would be used in a sentence like:

The parameter is selected from the set and used in the experiment.

I want one phrase for selected from the set so that it can be used to form a terminology.

Please supply a sentence in which you will use this word to better enable us to select the correct word for the job. How to Ask –  Matt Эллен Apr 23 '12 at 9:59
    
Either one parameter is selected, or multiple parameters are selected. Either way, "selected at random" (or "randomly selected") should work fine. –  J.R. Apr 23 '12 at 10:10
    
Is there a single adjective that signifies "randomly selected"? I really wanted just one word. I was thinking like "Drawn" - but wasn't looking very clear. Is there some other word? –  Dipan Mehta Apr 23 '12 at 10:15

Random can be used as an adjective ("Pick 2 random numbers," e.g.), but you have been so vague in your example that I don't have enough context to recommend for or against such use (which is also why I've voted to close). –  J.R. Apr 23 '12 at 10:46

@DipanMehta: When talking math in words, being precise is more important than being succinct with words. The sentence you have provided is clear enough if you specify randomness: The parameter is chosen randomly from the set and used in the experiment. –  Bravo Apr 23 '12 at 13:37

You could say:

A parameter is drawn and used in the experiment.

The definition for this use of draw is "to hold a drawing, lottery, or the like: to draw for prizes." The connotation is that a drawing is a random picking of the "winner." I think I would change the article from The (definite article) to A (indefinite article), though. Also, it needs to be clear from what preceded this sentence that there was a set from which this particular parameter was drawn.

We select an arbitrary parameter from the set.

-1: There is a big difference in math between arbitrary and random and the OP is only talking about picking a random parameter. –  Bravo Apr 23 '12 at 12:45
    
@Shyam, OP says "randomness is implied but not necessary" so latter half of your comment is incorrect. –  jwpat7 Apr 23 '12 at 13:01

@jwpat7: Well, the title says random. Moreover I can tell apart necessity and sufficiency, but I do not understand what the OP means by implied but not necessary. If you pick a ball from a bottle of balls and if it is provided that all balls are equally likely to be picked, then you are picking randomly (according to a uniform dist.) and not arbitrarily... Not sure if the OP means this only. –  Bravo Apr 23 '12 at 13:06
    
arbitrary # random. –  Kris Apr 23 '12 at 13:51

Arbitrary usually means "any" in math, meaning the result is the same in any case. Random refers to a type of selection. The words are not synonymous. In this case, the type of selection could be random or not, so it is arbitrary. –  Eli Rosencruft Apr 23 '12 at 14:59

"random" is the appropriate and usual term.

If you must use another, blind can be an alternative, which is also technically recognized and applied, as in blind study.

Tx @jwpat7 - done. –  Kris Apr 23 '12 at 13:13
    
Wasn't a verb requested? Can you show how you would use your suggested words to complete the OP's sample sentence? In my field a blind study means (in the simplest terms) the researcher recording the observations does not know which subjects were placed (by a different researcher) in the experimental group and which in the control group. I'm not sure how you are using the term blind. –  JLG Apr 23 '12 at 13:23
    
extract (v.) should do. However, you can see that I was suggesting a (n.) rather. From title down to last sentence, the OP is not consistent in his 'required phrase'. btw you're right about 'blind'. –  Kris Apr 23 '12 at 13:49
    
"selected from the set" can be noun phrase, qualifier, or verb pt, depending on use. right? –  Kris Apr 23 '12 at 13:55
    
Blind is just right - but since i wanted to use it in some naming convention, it had other connotations which i wanted to avoid –  Dipan Mehta Apr 24 '12 at 5:27
