Primary Data vs. Secondary Data: Know the Difference
By Shumaila Saeed || Published on January 23, 2024
Primary Data is data collected firsthand for a specific research purpose. Secondary Data is data previously collected for another purpose but used for a different study.
Key Differences
Primary Data is gathered directly from the source, tailored to the researcher's specific needs. Secondary Data, conversely, is collected by someone else, originally for a different purpose, and later used in research.

Primary Data is often more accurate and reliable for the specific research question since it is collected firsthand. Secondary Data might not be as precisely relevant to the researcher’s specific question, given it was collected for other reasons.
