Which type of research uses pre-existing data from past studies and sources?

• A. Primary Research
• B. Field Research
• C. Secondary Research
• D. Experimental Research

Answer: (C)

The concept being tested is using information that already exists instead of collecting new data. Secondary research involves analyzing pre-existing data from past studies and sources such as academic articles, government reports, and databases. This contrasts with primary research, where new data is gathered firsthand—often through surveys, interviews, or experiments. Field research is a form of primary data collection conducted in real-world settings, while experimental research involves manipulating variables in a controlled environment to observe effects. Because secondary research relies on data that has already been produced, it’s ideal for building background knowledge, identifying trends, and saving time and resources, but it may be limited by the relevance and quality of the available data.
