I would just like to thank eveyone on wikipedia, who edits and creates such acurate articles. Because they're not articles that we our selves should be fighting over (expecially the historical articles where people think they have a claim to the article, because of their 'expert knowledge), they are articles for OTHER people to read as a reference, to help them with their studies. This particular article has helped me understand the term 'decile' in my statistics paper. Thank you.
