Maths restored
I've restored the mathematical section, which is useful for those who want to know the maths. I've also done some general tidying and clarification. Note that the definition that a correlation is only valid if the two variables are ratio variables is too strict; they only need to be continuous variables. HSpalding 16:57, 5 January 2009 (EST)
