ABSTRACT
This chapter provides a comprehensive overview of data collection methods in social science research, bridging traditional approaches and modern digital innovations. It first reviews established quantitative instruments – such as structured surveys, standardized tests, and systematic observations – and classic qualitative techniques like in-depth interviews, focus groups, participant observation, and archival research. The chapter then demonstrates how these methods have been transformed or augmented by technology: for example, surveys can now be administered via online platforms or mobile apps to reach broader populations, social media and digital traces serve as new observational data sources, and emerging tools like crowdsourcing or wearable sensors contribute novel data streams. Practical considerations are highlighted throughout, from sampling strategies and measurement reliability for quantitative tools to building rapport and credibility in qualitative interactions. The chapter also underscores essential ethical safeguards (like informed consent and data privacy protection) in both face-to-face and online data collection. Overall, readers see how digital advancements have extended researchers’ reach and efficiency while requiring careful attention to data quality and research ethics.
