Final answer:
True, biographical information should be removed to protect participants' privacy. Researchers must follow ethical guidelines to anonymize data and handle it responsibly.
Step-by-step explanation:
Biographical information should indeed be removed prior to the publication of the results to protect participants' privacy. This is essential in research ethics where privacy and confidentiality are of utmost importance. Researchers have a duty to ensure that any data that could potentially identify a participant is either removed or sufficiently anonymized before publication. This standard is reinforced by ethical guidelines set by organizations such as the American Sociological Association, which emphasize the protection of privacy and the responsible handling of confidential information. Additionally, issues of informed consent and the appropriate handling of biological materials are also crucial ethical considerations in research.
