Secondary research is a research method used to collect data that has already been collected by someone else. This type of research is often used in the social sciences, where researchers can analyze existing data to answer new research questions. Common research methods include literature reviews and meta-analyses.
One advantage of secondary research is that it can be conducted relatively quickly and cheaply since the data has already been collected. Additionally, secondary research often provides a broader perspective than primary research, as it can include data from a variety of sources.
Disadvantages of secondary research include the potential for outdated or irrelevant information, as well as the fact that the data may not be specifically collected with the current research question in mind. Additionally, secondary data may be of lower quality than primary data, as it is often collected by organizations for other purposes.
When conducting secondary research, it is important to carefully consider the source of the data and to evaluate its relevance and accuracy. Additionally, secondary data should be used in conjunction with other research methods, such as primary research, to ensure a well-rounded perspective.
It is a common technique used in market research and other business-related research.
