Ratings and ranks; we love them and regularly use them to gauge our thoughts and feelings about places and events in our lives. Cars are rated on various performance criteria and then ranked against one another. Athletes are similarly rated on their performance and then ranked in comparison to others. In olympic figure skating, for example, a high rating produces a rank close to the top of the scale, with the high~ est rating producing the winner (the person ranked first) . The Nielsen Co. reports that a certain TV show has 23% of the market for its time slot.
