Primary Research: Primary research usually means a primary source. For example, Primary Research can be interviewing someone, conducting research. Other examples can be observations, case studies, surveys, experiments etc. The individual directly collects information from the experiment.
Secondary Research relies on secondary sources for example using a book to prepare for a report. Secondary data can be books, articles published, statistical data, reports, and case studies.
So basically, primary research is direct contact to collect the data and secondary is using other sources rather than directly getting the information from the source. Hope this helps.
