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 appropriately resolve the discrepancy in temperature measurements, the scientist should perform the experiment again. Repeating the experiment allows for verification of the initial results and helps to ensure accuracy and reliability in the findings.
A) Only include data that matches the results from previous studies
This option is incorrect as it suggests altering the data to conform to previous findings, which undermines scientific integrity. Instead of selectively including data, the scientist should focus on validating their own results through further experimentation.
B) Perform the experiment again
This option is correct because it emphasizes the importance of replicating the experiment to confirm the initial findings. By conducting the experiment again, the scientist can identify any potential errors or anomalies in their original measurements and gain a clearer understanding of the reaction's behavior.
C) Publish the results as a contradiction to the previous studies
While this option acknowledges the discrepancy, it is not a constructive approach. Publishing results without further investigation could mislead the scientific community and does not address the need for verification through repeated trials.
D) Discard all of the data and report that the results should have matched previous studies
This option is incorrect as it suggests ignoring the collected data altogether. Discarding data without proper analysis denies the opportunity to understand the reasons behind the discrepancy and fails to contribute to scientific knowledge.
Conclusion
Performing the experiment again is the most appropriate course of action to resolve the discrepancy in temperature measurements. This approach prioritizes scientific accuracy and integrity by allowing the scientist to verify their findings, while all other options fail to address the need for reliable data and thorough investigation.
