In the second half, the Yankees have looked like a World Series caliber offense one week and looked like they were coming crashing down to earth the next. When things are going well, the Yankees will hit home run after home run and drive runners in from scoring position. When things are going badly, the strikeouts will pile up and runners will be stranded. Of course, any fan who follows his or her team on a day-to-day basis can go from planning the World Series parade to thinking about rebuilding within the span of a few days. But with the Yankees, the roller coaster ride has actual statistical basis. Going into Friday's games (September 4), the Yankees had the highest variance in runs scored, and it isn't very close: Variance measures how close a set of numbers is to their average. At 15.5, the Yankees variance in runs scored is almost 25% above than the next highest Toronto Blue Jays, The Seattle Mariners might not have the most high-powered offense, but it is more consistent than every other team, as their variance is the lowest in the MLB.
