Surveys, interviews, and case studies are common methods for collecting primary data. Surveys involve standardized questions to a sample, interviews use open-ended or structured questions with individuals or groups, and case studies provide in-depth analysis of a person, group, or organization through various data collection methods. Other primary data collection methods include observations, experiments, action research, and data from sensors, measurements, user inputs, events, machines, and business processes.
