Stats >> Steps in a Typical Data Analysis (January 26, 2000)

Humans are good ... at discerning subtle patterns that are really there, but equally so at imagining them when they are altogether absent. Carl Sagan (1985) Contact.

"Isn't it interesting that the same people who laugh at science fiction listen to weather forecasts and economists?" Kelvin Throop III, as quoted in http://www.w2knews.com/index.cfm?id=453.
