As noted, qualitative and quantitative research categories are broad, and each contain many sub-categories and the possibility of mixed methodologies. From a perspective of ease and clarity, quantitative experiments are often more cost-effective, and seek to generally show the attitudes and beliefs of a given population, or segment of the population, regarding an established issue. Many academic researchers use survey research to find these attitudes and beliefs, because it introduces the subject of the mixed methodology when these survey results are presented in graph and chart forms. "Surveys can be classified by their method of data collection. Mail, telephone interview, and in-person interview surveys are the most common. Extracting data from samples of medical and other records is also frequently done. In newer methods of data collection, information is entered directly into computers". In today?s world, academic researchers may also conduct surveys over the internet or in instant message programs.
Conducting a mixed methodology research project, an academic researcher may also want to go the route of looking at conclusions drawn from existing research. This can be a qualitative or quantitative approach; the key is that the academic researcher uses the studies and research of others that is established, to make their own points. This type of method is sometimes called a meta-analysis, but in reality, it is more like an extended sort of literature review. The researcher supports or dissents regarding the points of other researchers, based on a past precedent.
Although there are many ways of approaching academic research, the two most common categories for research methodologies are qualitative and quantitative. Research can, however, have elements of both categories, and still be effective. Quantitative research may be higher in terms of reliability and validity for academic researchers, but may not bring across the human element of the research to the reader as well as qualitative research. This latter form of research, while presenting a more human face, may also be construed by the reader as being too subjective. In establishing a research methodology, the adept academic researcher may pick and choose from both quantitative and qualitative elements.
