Which principle is demonstrated by reducing data collection to the minimum necessary for analysis?

• A. Public disclosure of all data.
• B. Data maximization.
• C. Data minimization for privacy.
• D. Ignore privacy concerns.

Answer: (C)

Data minimization for privacy focuses on gathering only what is truly needed to achieve the analysis, and nothing more. By limiting collection to the minimum necessary, you reduce the amount of sensitive information exposed, lower privacy risk, and keep data handling simpler and more secure. This approach still lets you perform meaningful analysis because you retain only data relevant to the specific purpose and discard extraneous details.

Disclosing all data would undermine privacy, and collecting more data than needed increases risk without added analytical benefit. Ignoring privacy concerns is unethical and unacceptable.
