Final answer:
Secondary marketing research data can be sourced from peer-reviewed journals, reputable organizations' publications, academic books and articles, college library databases such as JSTOR, and the MLA International Bibliography, as well as reports and statistics from international organizations like the WHO.
Step-by-step explanation:
Sources of secondary marketing research data are essential for professionals to supplement their own primary research. Consider using a mix of the following reputable sources:
- Peer-reviewed journals for high-quality academic insights.
- Publications from respected organizations for broad societal trends.
- Books and articles from other authors providing in-depth analyses.
- College library databases, such as JSTOR, focused on humanities research.
- The MLA International Bibliography for cultural studies.
- Reports and statistics from international organizations like the WHO.
Using these sources ensures that the research is nonreactive, meaning it does not influence the subjects' behavior as there is no direct contact. Furthermore, documenting and citing these sources carefully is crucial, and researchers can refer to the tools available from the Modern Language Association or APA guidelines for proper documentation. Always remember to verify the credibility of your sources and keep a detailed record for appropriate referencing.
