Empirical analysis of data acquisition techniques: PAPI vs. CAPI

Data acquisition refers to the act of collecting data on a large scale. This paper presents a qualitative and quantitative analysis of two data acquisition techniques, namely, Pen and Paper Interviewing (PAPI) and Computer-Assisted Personal Interviewing (CAPI). It cites two case studies to clearly define the difference between the two techniques. They have been compared on four factors, namely, cost, time consumed during the whole process, productivity of each interviewer and quality assessment of each techniques (average number of errors occurred per interview). It emphasizes on providing absolute numbers to clearly show the difference between the two techniques.
