Give an example of a set of sports data that can be grphed and use to make a prediction?

Scores for gymnastics. All sports can be graphed. Gymnastic's have scores such as 7.5, 8.7, 9.0, ect. Perhaps if your focus was on one athlete, you could record there personal scores for a season or such. For football, you could take a player and recored the number of touchdowns that individual has done that season or the past years. By doing so you can predict if the athlete has improved or not.
