George has been collecting data for his science fair project which focuses on how different amount of fertilizer affects the growth of bean plants. He tested 5 different plants and gave each a different amount of fertilizer for a period of 10 weeks. Which of these should George incorporate into his display board in order to best visually represent all of his findings?
George should incorporate the plant which he gave the least fertilizer and the plant which he gave the most fertilizer, because those will show the biggest difference.
