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 core principle of the scientific method at issue is reproducibility. When experimental results deviate significantly from established findings, the first and most crucial step is to verify the result. Repeating the experiment allows the scientist to check for potential systematic errors (e.g., miscalibrated equipment) or random errors (e.g., procedural mistakes) that may have occurred during the initial trial. This process ensures the anomalous data is a genuine, repeatable observation before any further conclusions, such as challenging previous work, are made. This adherence to rigorous verification upholds the integrity of the scientific process.

A. This is selective data reporting, or "cherry-picking," which is a form of scientific misconduct that biases the outcome.

B. Publishing without first verifying the anomalous result through repetition is premature and scientifically irresponsible.

D. Discarding valid data and falsifying a report to match expectations constitutes scientific fraud.

In the section "The Treatment of Data," it is explained that unexpected or anomalous results require careful consideration and often further investigation, such as repeating the experiment, to determine their cause (p. 17). https://doi.org/10.17226/12192

In the section "A.2: Types of Experimental Errors," the manual discusses systematic errors, which can cause results to be consistently high or low. The primary method for identifying and correcting such errors is to "recalibrate equipment" and "repeat the experiment," reinforcing the need for verification (p. 10).

If a result cannot be reproduced, it is not considered a valid scientific finding (Chapter 1, "The Scientific Method," para. 4).
