Which term describes data that is gathered from sources other than the user?

• A. Primary data
• B. Secondary data
• C. Physiological factor data
• D. Perception

Answer: (B)

Data gathered from sources other than the user is secondary data. This means the information already exists somewhere else—published reports, statistics, textbooks, or datasets created by someone else for a purpose other than your current project. You’re using it second-hand rather than collecting it yourself for this study. In contrast, primary data is collected directly by you from participants or sources for your specific purpose. The other options don’t fit because they describe a different concept: physiological factor data refers to measurements of the body's signals, which is a type of data, not about where it comes from; perception is the process of interpreting stimuli, not a data source. So the best term for data sourced from elsewhere is secondary data.
