Experimental Design A friend of yours, who is an avid gardener, recommends Brand X fertilizer to use when growing your bean plants this summer. She indicates that this is the best brand of fertilizer. You notice that this brand is much more expensive than its competitors, and you are not sure if it is worth the added cost. You decide to conduct an experiment to test the hypothesis: X brand of fertilizer increases the yield of bean plants. Questions 1. How can you improve this hypothesis? Rewrite it to be testable and falsifiable. 2. What is the null hypothesis to this experiment? 3. Predict the data that will support the hypothesis: 4. Predict the data that will support the null hypothesis: 5. What is the independent variable in this experiment? 6. What is the dependent variable in this experiment? 7. Is the dependent variable quantitative or qualitative? 8. How will you measure the dependent variable? 9. How will you analyze the dependent variable? 10. How many experimental groups will you use and how many replicates will be in each group? Why do you think this is a sufficient number of groups and replicates? 11. Other variables that can affect bean yield Ways to minimize the effect of this variable in your experiment 12. Provide a description of your experimental design and how you plan to run your experiment. Make sure your description is clear enough that someone else could replicate your experiment correctly.
