What is secondary research primarily based on?

Secondary research is primarily based on the analysis and synthesis of already published data and information. This includes gathering insights from existing books, periodicals, articles, and various other sources that have previously documented research findings or information relevant to a particular topic. The aim of secondary research is to use this existing body of knowledge to draw conclusions or to further understand an area of interest without the need for original data collection.

In contrast, primary research involves new data collection through methods such as interviews, surveys, or experiments, whereas secondary research focuses on utilizing and interpreting information that is already available. Thus, the emphasis on reading books and periodicals makes this choice suitable as it aligns directly with the definition and practice of secondary research.
