useful data
not useful

Explanation:

To determine if the project improved biodiversity at this specific coral reef, we need data related to this reef's biodiversity before and after the project, and other projects at this reef (as they might affect results). Data about all coral reefs is not specific to this reef.

• Useful Data:
• Animal diversity after the project at this coral reef (shows post - project biodiversity at the target reef).
• Other projects at this coral reef during that time period (to account for other factors affecting biodiversity at this reef).
• Animal diversity before the project at this coral reef (shows pre - project biodiversity at the target reef for comparison).
• Not Useful:
• Information about animal diversity in all coral reefs (not specific to the Florida coral reef in question).

Answer:

Useful Data

• Animal diversity after the project at this coral reef.
• Other projects at this coral reef during that time period.
• Animal diversity before the project at this coral reef.

Not Useful

• Information about animal diversity in all coral reefs.
