In collegiate football, ties are now rare, only two percent of the games ending this way in 1967, the highest scoring tie being 37–37. Ties happen less than half as often as one-point differences. The most frequent outcome of a game was 14–7, although the most frequent winning score was 21 and the most frequent losing score was 0. The average winning score was 27, the average losing score, 10. A team score of 11 has a 25 percent chance of being a winning score, a score of 16 a 50 percent chance, a score of 23 a 75 percent chance and a score of 40 is practically certain to win, based on a freehand curve. Scores of 3, 9, 10 are more favorable to winning than their size would suggest, while 18 and 22 are less favorable than theirs suggests. Indeed, a score of 9 is more likely to win than is a score of 15, and nearly as likely as a score of 18.
