Statistics - they're all around us, and we're exposed to them every day. They allow us to summarize large volumes of mathematical information, and so are found wherever there's data to be presented. Let's say you're watching your favorite college football team, and the game has come down to a last second thirty-five yard field goal attempt for the win. When describing the kicker's past performance in this range, the play-by-play announcer doesn't list all of the kicker's attempts one by one and their outcome, he simply states the percentage of kicks made in this yard range. If the kicker's success rate between 30-40 yards has been 90% this season, then you're feeling pretty confident of victory. If it's 40%, you're gripping the chair a little tighter when the ball is snapped.
