Tina conducted an experiment to test her hypothesis. Her hypothesis was that by crushing aspirin and putting it into potting soil increases the growth rate of tomato plants. The results of the experiment show that there was no significant difference in the growth rates between the control and the experimental groups. What should Tina do with the results of this experiment?
Tina should think about results and why aspirin did not affect the growth rate of tomato plants. She may find the answer in literature or can apply the results on the new situation. She may change the hypothesis and alter some factors in the experiment to test the new hypothesis.
