Primary data refers to information that is collected by the researcher specifically for the research project at hand. Different research problems may require different types of primary data collection methods, including surveys, observation, registration and experiment.

One of the most popular methods is the survey, which is used in different forms including:

  • person-administered surveys
  • computer-administered surveys
  • self-administered surveys
  • hybrid surveys, which use multiple data collection methods
