As an aside, I have a pretty thorough understanding on both probability and statistics. I taught both on a college level. I always find it interesting when anyone without a statistics degree interprets statistics or evaluates another persons interpretation of the same numbers. Many of these interpretations are quite helpful but all have to be considered with caution. The first question that I like to ask someone claiming to understand or interpret statistics is: "What is a statistic?". Many people think that statistics are numbers but what exactly is the mathematical definition of a statistic. You won't find it in the dictionary. How can we talk about something without even the most basic definition of what it is? Stay tuned, if interested, for the definition in an upcoming issue of the LML. > From: Brent Regan > >> Terrence writes: >> <> the airlines report safety in terms of passenger miles?
