Exercise 1: Data Interpretation
Table 1: Water Quality vs. Fish Population Dissolved Oxygen | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | Number of Fish Observed | 0 | 1 | 3 | 10 | 12 | 13 | 15 | 10 | 12 | 13 |

1. What patterns do you observe based on the information in Table 1?
One pattern I observe was in the number of increments. ie….0,1,1,4,4,3,3,4,4,5. The increments would stay the same between for two observation periods with the exception of the 1st and last observation period.

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.
If the amount of dissolved oxygen increases in water then the amount of fish will also increase.

3. What would your experimental approach be to test this hypothesis?
My experimental approach to test my hypothesis would be to measure the dissolved oxygen in different areas of a body of water and keep track of the fish in those areas. Then I would compare the results.

4. What are the independent and dependent variables?
Dissolved oxygen would be independent variable while fish would be dependent.

5. What would be
