Preliminary research is research that contains information that needs to be verified and its results are not conclusive. This kind of research is usually used to get an idea about a particular topic and to discover the amount of information that is available on the topic.
Conducting preliminary research involves choosing a topic that is interesting. Finding enough background information on the topic is vital in developing a research question. This allows the researcher to focus on the specific information they want. A preliminary research topic may be promoted to established research if the details are confirmed after the follow-up research is conducted.
