Exercise 1: Data Interpretation
Table 1: Water Quality vs. Fish Population
Dissolved Oxygen024681012141618
Number of Fish Observed01310121315101213

1.What patterns do you observe based on the information in Table 1?

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 would be your control?

6.What type of graph would be appropriate for this data set?

7.Graph the data from Table 1: Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then “Insert” the graph, or use another drawing program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here.

8.Interpret the data from the graph made in Question 7.

Exercise 2: Testable Observations

Determine which of the following observations (A-J) could lead to a testable hypothesis. 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?

When a plant is placed on a window sill, it grows three inches faster per day than when it is placed on a coffee table in the middle of the living room. .

I will analyze the data between the two control groups and note the differences.
