Look for the definition of "centroid" in your book. In my textbook, the answer is "yes" (if "cloud" means "finite set"). –  GEdgar Feb 22 '12 at 14:23

Thanks for the reply, i saw the wikipedia page, but wasn't sure if my interpretation was correct. –  user25251 Feb 22 '12 at 15:19

The comments state that 'arithmetic mean of coordinates' is indeed the definition of the centroid.
