CATI, or Computer-Assisted Telephone Interviewing, is a method of conducting surveys and collecting data through telephone conversations with the assistance of computer software. This technique allows for efficient and accurate data collection by providing a structured questionnaire and real-time data entry, eliminating the need for manual data entry and reducing human error. CATI is commonly used in market research, political polling, and social science research, providing a cost-effective and reliable way to gather information from a large and diverse population. With the advancement of technology, CATI has evolved to include features such as call recording, call scheduling, and real-time data analysis, making it an essential tool for businesses and researchers seeking valuable insights and data-driven decision making.
