What type of research focuses on collecting data from a small number of subjects to study phenomena in depth?

Qualitative research is centered on exploring and understanding human experiences, behaviors, and social phenomena through in-depth data collection methods. It emphasizes the richness of individual experiences rather than statistical analysis. In qualitative studies, researchers often engage with a smaller number of subjects to delve deeply into their perspectives, allowing for a comprehensive understanding of complex issues. This approach is particularly valuable in fields like nursing, where patient experiences and perceptions can provide crucial insights into care practices and patient outcomes.

In contrast, quantitative research typically involves larger sample sizes and focuses on numerical data and statistical analysis to identify patterns and relationships. Integrative reviews synthesize findings from multiple studies, while meta-analysis combines data from various studies for statistical evaluation, neither of which prioritize in-depth analysis of individual experiences. Thus, qualitative research is the most fitting choice for studying phenomena in depth with a limited number of subjects.
