A group of students is designing an experiment to test the effectiveness of different fertilizers on bean plant growth. They have three groups of plants: Group A receives Fertilizer X, Group B receives Fertilizer Y, and Group C receives no fertilizer. All plants are grown in the same type of soil, receive the same amount of water, and are kept in the same location. They measure plant height daily for two weeks.
Critique this procedure. What are its strengths and weaknesses? Suggest any improvements you would make to ensure more reliable and valid results.
