What Are the Methods of Primary Data Collection?

The most common methods of collecting primary data are conducting questionnaires, surveys, interviews, observations, case studies and focus groups, and examining documents and records. Data collection is the process of gathering information from different sources.

There are two types of data: primary and secondary data. Primary data is information obtained directly from first-hand sources, while secondary data is information that has already been collected by another person for other studies. One of the differences between the two types of data is that secondary data takes less time to obtain, while primary data takes more time because the information has to be gathered from scratch.

Secondary data is obtained from books, diaries, newspapers, statistics, Internet articles, databases and interview transcripts.
