Exercise 1: Data Interpretation
Table 1: Water Quality vs. Fish Population Dissolved Oxygen (ppm) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | Number of Fish Observed | 0 | 1 | 3 | 10 | 12 | 13 | 15 | 10 | 12 | 13 |
(hint: ppm stands for “parts per million”) 1. What patterns do you observe based on the information in Table 1?
Ans. The quality of fish increase as (ppm) increase to a point while the quality of water continue to increase 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. Ans: If oxygen or ppm in the water increase more fish will be produce

3. What would your experimental approach be to test this hypothesis? Ans. My experimental approach will be gather data, by doing background research, and test experiment by having a independent, and dependent variable. I will analyze my result and make conclusion

4. What are the independent and independent variables? Explain why each was chosen. Ans. My dependable variable will be water with high level of (ppm) which will increase
