54. A scientist measures the change in temperature from a chemical reaction over a three-day period in a single experiment. When the scientist analyzes the data, the results are five degrees Celsius higher than reported by other scientists after studying the same reaction. How can the scientist appropriately resolve this problem?
Answer: B
Perform the experiment again
To resolve the discrepancy in temperature measurements, the scientist should perform the experiment again. This approach allows for verification of the original results and helps identify any potential errors in methodology or measurement.
A) Only include data that matches the results from previous studies
This option is incorrect as it suggests cherry-picking data to align with past studies, which undermines scientific integrity. Valid scientific conclusions must be based on comprehensive and accurate data, not selective reporting.
B) Perform the experiment again
This option is correct as repeating the experiment can confirm the initial findings and ensure the reliability of the results. It provides an opportunity to investigate any inconsistencies and refine the experimental process, leading to more accurate conclusions.
C) Publish the results as a contradiction to the previous studies
While publishing contradictory results can be valuable, this option does not address the need for verification through repeated experimentation. Without confirmation of the new findings, publishing could lead to misinformation and lacks the rigor expected in scientific research.
D) Discard all of the data and report that the results should have matched previous studies
This option is incorrect as it suggests ignoring valid data simply because it does not align with past findings. Discarding data without further investigation is not a scientifically sound approach and could lead to loss of potentially important information.
Conclusion
Performing the experiment again is a thorough and scientifically sound method to address the discrepancy in temperature measurements. This approach ensures that the results are accurate and can be reliably compared with previous studies. The other options either compromise scientific integrity or do not adequately address the issue, making them less appropriate for resolving the problem.
