The line chart compares the number of participants who engaged in various special activities at a sports center in Melbourne, Australia, over a period of 20 years, from 2000 to 2020.
At first glance, it is evident that the number of participants in musical performances and table tennis increased over time, while the category of amateur drama experienced a significant decline. Additionally, the film club had the highest number of members among all activities.
Upon closer examination, it becomes clear that musical performances increasingly appealed to local residents. In the first five years, the musical club had no members. However, this number steadily rose to 15 members over the next 15 years. The table tennis club, like the musical club, exhibited a similar upward trend; however, the number of table tennis players reached three times that of the musical club. By 2020, the number of table tennis participants peaked at over 50.
In stark contrast, the number of participants in the Amateur Dramatic Club saw a slight decline. It initially rose from 25 to 30 participants in 2005 before dropping to fewer than 10 by 2020.
Regarding the Martial Arts club, the number of participants fluctuated between 30 and 40 members over the time period in question. Similarly, the film club maintained a stable membership, which was higher than the combined totals of the other activities. Although there was a minor decrease in membership in 2010, it was not substantial.
