Question
A student wants to conduct a science fair project about the effects of different types of fertilizers on plant growth. His teacher tells him that he should use repeated trials in his experiment. Why should the student use repetition in his experiment?
to practice the procedure for conducting scientific experiments
to allow his classmates to conduct the same experiment to confirm his results
to provide him with results from a group with which to compare the experimental treatment
to ensure that his experimental results are accurate and the experiment did not contain flaws

The best reason for the student to use repetition in his experiment is:
**to ensure that his experimental results are accurate and the experiment did not contain flaws.**
Repetition helps to confirm the reliability of the results by minimizing the impact of random errors and variability in the data, leading to more robust conclusions about the effects of different types of fertilizers on plant growth.
