Do they have the same problem if you restate it in terms of percentages? So, if p= 5%, circle which of the following is smaller:
a) 1% b) 10% c) 3% d) 6% If they can't do this, then your students in are in real trouble. Then again, if you re-frame it into: If cost = $5, circle which of the following is smaller: a) $1 b) $10 c) $3 d) $6 If they can't do this, then I have some investments I'd like to talk to them about. -Mike Palij New York University [email protected] ----------------- Original Message ---------------- On Fri, 28 Sep 2012 15:11:29 -0700, Beth Benoit wrote: Karl, Is it possible they're having trouble with the < vs. the >?

I know, it "ain't rocket science," but I suspect a lot of people never had that explained to them. *Please* say that's what it really is. ;-) Beth Benoit Granite State College Plymouth State University New Hampshire On Fri, Sep 28, 2012 at 5:43 PM, Wuensch, Karl L <[email protected]> wrote: > I am not the greatest fan of NHST, but do my duty to teach it.
