My final quantitative assignment explores the relationship between age and schedule/utilization (# of tournaments played annually) for professional tennis players. Players typically travel from a place to a place every week to compete in tournaments so a professional tennis career is associated with more traveling than other sports (whose players may stay at their home base 50% of time or within one country mostly). The hypotheses that this analysis will inform are:
- Do players tend to reduce their schedules as a result of fatigue or fear of injury as they age? --> Not supported by the data since "older" players (30-35 in age) still play 20-25 tournaments per year (although on average they drop 1.5 (men)-2 (women) tournaments). There is a drop after age 35.
- Is there a difference by gender? --> Yes, the data suggests that men play more tournaments earlier in their careers (ages 18-30) but then women outplay men in later ages (30-33).
The original sketches explored several different ways to establish a relationship between age and utilization. Most of my peers really liked the circle diagram, so I refined it and included a comparison of men vs women.
