When investigating the relationship between weather and bus ridership, it is essential to focus on data that directly correlates the two variables. Collecting the mean number of bus riders on rainy days specifically allows for a clear analysis of how bus ridership is affected by inclement weather. This information can be compared to ridership data on days when the weather is different, such as sunny or dry days, to assess any significant patterns or trends.

Gathering data on the mean number of riders on rainy days enables researchers to draw direct correlations between rainy weather and ridership levels. This comparison can reveal whether rainy conditions lead to increased or decreased use of the bus service, thereby providing valuable insights into the impact of weather on students' transportation choices.

In contrast, options that examine data outside of this focus, such as the total number of rainy days or the number of students who do not ride the bus, do not directly contribute to understanding the impact of weather on bus ridership. Therefore, collecting data specifically about bus riders on rainy days is the most relevant approach to explore this relationship effectively.
