The line graph illustrates the number of participants in four different types of sports in one region between 1985 and 2005. Overall, the figures for tennis and rugby experienced significant increases and decreases following contrasting trends, while basketball and badminton showed unchanged trends.
Focusing first on the higher figures, rugby started with just under 250 players in 1985. The numbers then followed a downward trajectory for the rest of the period and eventually ended at only 50. The count of tennis participants, on the other hand, despite starting lower than rugby at almost 150 players in 1985, rose significantly to finally peak at 250 in 2005, becoming the leading sport.
When it comes to basketball and badminton, both figures showed stable trends. Basketball began with 75 players, after which no notable changes occurred, and the number of players remained almost the same even after 30 years. A similar pattern was mirrored by badminton, which also showed no noticeable change, remaining constant at 50 players throughout the period.
