Exercise 1: Data Interpretation
1. What patterns do you observe based on the information in Table 1?
- The more dissolved oxygen in the water the more fish they observed.
2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.
- Having more dissolved oxygen increases the number of fish observed in the body of water.
3. What would your experimental approach be to test this hypothesis?
- To test this hypothesis my experimental approach would be testing different bodies of water or testing one and just testing different areas while tracking the fish.
4. What would be the independent and dependent variables?
