Question

Example 2 (5 points) Researchers at a university want to know if higher levels of nitrogen in fertilizer will increase the production of tomatoes per plant. Twenty plants are given normal levels of nitrogen and twenty other plants are given ten percent higher levels throughout the growing season. The plants receive the same levels of sunlight, water and are planted in the same soil on one farm. At the end of the experiment the average number of tomatoes produced is the same for each group. The scientists repeat the experiment on two additional farms further south that season. The researchers conclude that increasing nitrogen levels by 10% in tomatoes is not beneficial. Would this be a well-designed reliable experiment? Support your decision with at least three reasons.

Answer 1

The experiment was well designed.

What is an experiment?

An experiment is used to determine cause and effect relationships. We know that in this case, the research is aimed at being able to obtain the relationship that exists between the amount of nitrogen in the soil and the production of tomatoes per plant.

As we could see, the experiment includes a control that serves as a baseline for determining the validity of the results. Further more, the  sunlight, water and soil were held constant. The experiment was even repeated further south to verify the results.

Based on a careful review of the experiment, the experiment was well designed.
