Statistics are used throughout science both by those proposing a conclusion and those opposed to said conclusion.
Statistics form the basis for a wide variety of claims made about environmental, medical, and toxicological matters. I would even go so far as to note that they are often utilized by charlatans to give the illusion of analysis and certainty, when no such conclusions are justified.
An interesting assessment and discussion of the problem one often encounters with statistics used in various studies can be found at http://www.sciencenews.org/view/feature/id/57091/title/Odds_Are,_Its_Wrong. I commend it to your review. A skeptical attitude toward any expert needs to be an attorney's SOP, especially in this age of Daubert. (See http://en.wikipedia.org/wiki/Daubert_standard for an overview of Daubert.)
