QUESTION
Exercise 1: Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water.
- What patterns do you observe based on the information in Table 4?
- 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.
- Determine and outline the best experimental approach to test this hypothesis.
- Identify what your independent and dependent variables would be?
- Identify any controls present in the data. Then, determine one additional control which could be used in the experiment to test your hypothesis?
- What type of graph would be appropriate for this data set? Why?
- Graph the data from Table 4: Water Quality vs. Fish Population (found at the beginning of this exercise).
- Interpret the data from the graph made in Question 7.
