In sports, the biggest and most important factor of success is victory. Winning is how one succeeds in a sport, and is what most tend to pay attention to. Whether you win or lose doesn't tell the whole story, and isn't enough to judge whether or not someone is actually good at the sport. Statistics are useful analysis measurements that are used to keep track of how individual competitors are performing. NASCAR is no different, with a plethora of different statistics that measure different aspects of each driver's performance.
