What is the Difference Between a Case Study and a Small-Scale Survey?

We explain the differences between case studies and small-scale qualitative surveys. They share many features, such as collecting qualitative data, but differ fundamentally. Case studies seek deep, holistic insights into a single, bounded entity, using multiple data sources for contextual depth. In contrast, small-scale qualitative surveys prioritise breadth, gathering varied perspectives across several individuals with less depth per participant.
