This is kind of embarrassing, but can anybody write out, in plain English, the centroid equation? I know there's a snappy one in Lcent, but I need to do it in java, and I can't work out how to get Dr. Elsea's little equation to work... I'm not a mathematician by any stretch of the imagination, so all the equations I've found online wind up giving me some funky characters that are truly Greek to me (literally). Ssomething like "sum the list, take the average, and..." as an explanation would be brilliant.

Thanks in advance.
