A psychology researcher finds an extreme outlier caused by a participant's misunderstanding of the instructions. Apply the strict methodological standards of outlier exclusion to describe what the researcher should do with their raw data file and what details they must include in their final research report regarding this outlier.
Question: A psychology researcher finds an extreme outlier caused by a participant's misunderstanding of the instructions. Apply the strict methodological standards of outlier exclusion to describe what the researcher should do with their raw data file and what details they must include in their final research report regarding this outlier.
Sample answer: The researcher must retain the original raw data file with the outlier intact rather than permanently deleting it. In their final research report, they must transparently state the number of excluded data points and specify the reason for the exclusion (the participant's misunderstanding).
Key points:
- Apply the data retention standard by keeping the original data file intact and not permanently deleting the outlier.
- Apply the transparency standard by stating the specific number of excluded data points in the report.
- Apply the transparency standard by reporting the specific reason (misunderstanding of instructions) for the exclusion.
Rubric: The response must apply the outlier exclusion standards by stating that the original data should be retained (not deleted) and the final report must disclose the number of exclusions and the specific reason for their removal.
