Variate

Defined:  Random. Variable.  It is a NOUN. (Merium-Webster Online.)

Do I have to use it in a sentence?  Statistics is not my strong suit.  Time for some research.

Try this forum entry by Subhotosh Khan on freemathhelp.com:  “z(x,y) = x2 + y2 – 1 is a bi-variate polynomial function. For each unique input (x & y), the function returns a unique output (z).

Yikes.  Turns out to be an appropriate word to publish for back-to-school.  But I didn’t just pick this term at random (random, get it?), I heard it used.  In a similar context, by the way.  Where? The Big Bang Theory.  It’s a fun show and in almost every episode you can pick up at least one good word to add to your active vocabulary.  Something one would expect from a bunch of science nerds!  But if you really want to learn the nuance of this word, you can learn all about math at Khan Academy.  (Would serendipitous describe finding two sources by the same last name?)

But how do I use it, you ask?  Substitute it for any noun (person, place, thing, etc.) that can be substituted.  It would be used in a generalized manner unless you are speaking math lingo.  You will have to find context in your own work or life for this one.
