Definition of Data Sources
Data sources refer to the origins from which information is obtained. These can be categorized into primary and secondary sources. Primary sources provide direct or firsthand evidence, such as survey results or interviews. Secondary sources compile and analyze primary data, including reports and academic articles.

Always verify an author’s qualifications to ensure they possess expertise in their field.
Relevance and Timeliness
Relevance and timeliness significantly impact the utility of data sources. A source must align with your specific topic.
