Hypothesis and Experimental Approach
Questions
1. Based on this information, what patterns do you observe?
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.
3. What would your experimental approach be to test this hypothesis?
4. What are the independent and dependent variables?
5. What is your control?
6. What type of graph is appropriate for this data set? Why?
7. Graph the data from Table 2 (above) in the space below.
8. Interpret the data from the graph made in Question 7.
9. Determine which of the following observations are testable.
For those that are testable:
Write a hypothesis and null hypothesis
What would be your experimental approach?
What are the dependent and independent variables?
What is your control?
How will you collect your data?
How will you present your data (charts, graphs, types)?
How will you analyze your data?
