Scientists have been studying threats to coral reefs. Some reefs around the Southeast shore of Australia have experienced increased threats while others in the Northwest shore of Australia have seen a decrease in threat. Explain the most effective way that scientists could use this information to design a new study aimed at developing reef protections.

The scientists have been studying threats to coral reefs. They have found that coral reefs in the Southeast shore of Australia have experienced increased threats while others in the Northwest shore of Australia have seen a decrease in threat. The most effective way the scientists could use this information to design a new study aimed at developing reef protections is the development of research plan to know the effect of chief independent variables like pollution, habitat destruction on coral reef which is a dependent variable.
