CAPI vs PAPI depends on project context, geography, and respondent profile.
CAPI (Tablet)
Real-time sync, validation, GPS. Best for urban, large-scale, real-time projects.
PAPI (Paper)
No tech dependency, works anywhere. Best for remote areas, sensitive topics.
Default: CAPI. Reserve PAPI for remote fieldwork or extremely long questionnaires. Pro tip: 80% CAPI + 20% PAPI hybrid.
