Yesterday we studied strikeouts/game and runs/game for teams
and found a ďcorrelation coefficient,Ē which is a number between -1 and 1. 1 means there is a perfect correlation, like the temperature in Fahrenheit and the temperature in Celsius. -1 means there is a perfectly negative correlation, like the amount I spend and my checking account balance. And 0 means there is no correlation, like the amount I spend and the temperature in Celsius.
Unfortunately, the number we found was not 1, 0 or -1. It was .54. So what does that mean?
Numbers are so clean. Until they arenít.
