Which are ethical requirements for data collection in research?

• A. Informed consent, voluntary participation, respect for privacy, and unbiased data gathering
• B. Deceptive practices to obtain data
• C. Mandatory publication regardless of results
• D. No notification of participants

Answer: (A)

Ethical data collection in research with human participants centers on protecting participants and ensuring integrity throughout the process. The best answer reflects informed consent so participants understand what the study involves and agree to take part, voluntary participation so they can choose without coercion, respect for privacy through confidentiality or de-identification of data, and unbiased data gathering that uses proper methods and reports findings honestly without manipulation. Deceptive practices violate consent and trust, so they’re unethical; mandating participation or requiring publication regardless of results conflicts with autonomy and scientific integrity; and not notifying participants breaches privacy and informed consent.
