CAPI, or Computer-Assisted Personal Interviewing, is a method of data collection in which a computer program is used to assist in conducting surveys or interviews with individuals. This technology allows for real-time data entry and analysis, making the process more efficient and accurate. CAPI is commonly used in market research, social science studies, and other fields where large amounts of data need to be collected and analyzed. It has revolutionized the way data is collected, providing researchers with a powerful tool to gather and analyze information in a timely and accurate manner. With CAPI, the days of paper surveys and manual data entry are long gone, making it an essential tool for modern research and data analysis.
