The line graph illustrates the changes in the number of people participating in four different sports – basketball, tennis, badminton, and rugby – within a specific region over a two-decade period from 1985 to 2005.
Overall, it is clear that tennis showed a general upward trend throughout this period, while rugby exhibited a contrasting downward pattern. Another notable observation is that badminton consistently had the fewest participants at various points over the timeframe.
At the beginning of the period, rugby was the most popular sport, with around 240 participants. However, this number fell dramatically over the subsequent years, reaching approximately 50 by 2005. In contrast, tennis started with about 150 participants in 1985 and peaked at around 230 by the end of the period. Consequently, the disparity between the two figures became increasingly pronounced by the midpoint of the timeframe.
In the latter part of the period, badminton showed negligible variation, maintaining around 50 participants, which made it the least popular sport throughout the years. Meanwhile, basketball had a consistent participation level of approximately 70. By the end of the period, another significant observation was that both rugby and badminton had similar participation rates, each around 50.
