I removed the following text:

PEDANTIC NOTE Contrary to the opinion of those not blessed with an English education it is important to distinguish between the notions of ratio and rate. A ratio is one number divided by another. A rate entails reference to the passage of time: miles per hour, new cases per year (incidence), etc. A rate is necessarily a ratio but not vice versa.

This does not seem to be related to the text of the article, and I don't believe it's accurate. GAdam (talk) 03:59, 27 December 2007 (UTC)

It's not entirely accurate (you could have a rate that refers to something other than time: price per person, miles per gallon, etc.), but even if it were entirely accurate, it doesn't belong in this article. WhatamIdoing (talk) 04:44, 3 April 2008 (UTC)
