Answer:
Data are characteristics or information, usually numerical, that are collected through observation. In a more technical sense, data are a set of values of qualitative or quantitative variables about one or more persons or objects, while a datum (singular of data) is a single value of a single variable.
Primary data sources include information collected and processed directly by the researcher, such as observations, surveys, interviews, and focus groups.
Secondary data sources include information retrieved through preexisting sources: research articles, Internet or library searches, etc.
