Averages

A friend was relating a conversation with a Californian about their 60 degree average days.  He was quick to point out that our Houston fall average has also been 60 degrees, but we've arrived at that average with swings from 40 to 80 degrees.  In this case, averages yield entirely different wardrobe needs.  This was just another reminder that when we are making decisions, we often need to know the supporting data, rather than just the average of the numbers.
