Hey, Julie, it seems like you should be able to use statistical
modeling to solve this problem, as long as you don't need an exact
count. Gallup interviews a thousand people and then predicts who's
going to win the next election. You could do the same—interview a
couple hundred representative visitors and then apply the ratio to
total attendance. You might have to do it anew each time you bring
in a new exhibit since attendance ratios would likely change, but
that would be true no matter what technique you use.
Chuck Howarth, Vice President
