Final answer:
To ensure that his results are reliable, Andrew should conduct his experiments meticulously, ensuring reproducibility, and be open to being proven wrong. He should also make sure that his results are measurable, repeat his experiment for consistency, and seek replication by other researchers.
Step-by-step explanation:
Andrew should take specific steps to ensure that his results are reliable when analyzing the amount of DNA produced by different fruits. First, he should be tested using experiments that collect evidence, which means methods should be clearly defined and followed with precision during the experiment. Andrew should also acknowledge that his hypothesis can be proven wrong, meaning he should approach the data without bias and be open to any outcome revealed by the evidence.
Furthermore, his results should provide measurable and reproducible outcomes, meaning that if other researchers were to repeat his experiment, they would be able to get similar results. This emphasizes the importance of replication, which is repeatedly conducting the experiment to verify results. Therefore, Andrew should repeat his testing to check for the consistency of the results, and if possible, have other researchers try to replicate his findings to add to the robustness of the data.
Andrew must also ensure that the data he collects is not confounded, which means that he must design experiments that control for variables that can affect the results. He should also follow the criteria for making observations or measurements, ensuring he applies the same level of rigor to both expected and unexpected results. By following these steps, Andrew will not only improve the reliability of his results but also contribute to the overall trustworthiness of the scientific inquiry process.
