You still don't get it. Statistics is a science. There is empiric evidence behind it. I do not have sufficient medical knowledge to prove my point. All I'm saying is that Turban's dependence on his statistical references is flawed because the statistics he cites have gathering methods and results that are flawed. He either needs a more accurate statistical study, by the empiric methods statistical gather and analysis demands, or he needs other justification, and so do you.
