Data ethics and privacy are crucial aspects of modern data science, addressing moral obligations in data handling and individuals' rights to control their information. These concepts encompass informed consent, bias mitigation, fairness, and data governance, aiming to protect privacy while enabling responsible data use. Key frameworks like utilitarianism and deontology guide ethical decision-making, while regulations such as GDPR and CCPA set legal standards. Practitioners must navigate complex issues including bias, fairness, consent, and responsible data handling to ensure ethical and privacy-preserving data practices.
