I stopped walking to take this picture of a sign.
"Why take a picture of the sign?" she asked.
"So I can show people I walked 10 miles today" I replied.
"No you didn't. It's like a quarter of a mile from where we started!" she said.
"Well, I have this government installed sign that says 10 miles, so I'm going with it!" was my final word.
The moral of the story; A single data point is all but useless, no matter how important it looks or how much you want it to mean something.
A sign saying '10 mile' means nothing by itself. It's needs reference to have meaning. Context. Perspective. Just so, a single data point on most any topic one can name is a meaningless thing without reference, context, and perspective.
Beware the lonely data... it can bite you right in the intelligence.
