What type of information does the researcher collect while observing bike riders at an intersection?

Observing bike riders at an intersection involves monitoring behaviors and actions that occur in a public setting. When individuals are engaged in activities such as riding bikes, especially in a location where they are visible to others, their actions can be considered public behavior. This type of information is typically straightforward for researchers to collect because it does not require consent in the same way that private behavior would. Public behavior can include how riders navigate the intersection, their interactions with other road users, and their adherence to traffic signals, all of which are observable without infringing on personal privacy.

Private information, on the other hand, would require knowledge of something that is not accessible to the general public, and private behavior relates to actions that would not typically be visible or observable by others, making these options unsuitable for this context. Public information refers to data that is accessible and can be shared without restrictions, but in this scenario, the focus is on behavior rather than data or facts, which further supports that the correct answer relates specifically to the observable actions of bike riders in a public space.
