Primary research involves collecting your own data through methods like surveys, interviews, focus groups, and observations. Secondary research involves analyzing existing research from sources like the internet, newspapers, and libraries. Focus groups are a primary research method where a moderator facilitates a discussion among a group of people to understand opinions on a topic. Questionnaires are also a primary method where participants fill out a form with questions to gather data. The internet, books, archives, and articles provide sources for secondary research. Online libraries allow searching for books on topics to support research. Sources need to be evaluated for reliability.
