Primary data is information collected by the researcher directly through instruments such as surveys, interviews, focus groups or observation. Tailored to his specific needs, primary research provides the researcher with the most accurate and up-to-date data.
Secondary data, on the other hand, is basically primary data collected by someone else. Researchers reuse and repurpose information as secondary data because it is easier and less expensive to collect. However, it is seldom as useful and accurate as primary data.
Many experienced researchers use a combination of both primary and secondary data, conducting secondary research first, and then following up with primary research to fill any gaps in the study. This gives researchers a more comprehensive picture.
