How to choose the best methods

How to choose the best methods
This is a very complex issue and depends on many factors, not least practical ones – including the amount of time, money and expertise that a researcher has. However, as a general principle, it is worth emphasising that no one method is universally superior. Part of any research psychologist’s role is to make judgements about the appropriateness of a method for investigating the issues at hand. Being a good researcher is not a question of whether you do experiments or surveys: it is more a matter of when and how you do them. In view of the potential limitations of any one method, many researchers consider using multiple research methods to explore the same issue in many different ways. This is the process of triangulation. If consistent results are obtained from a variety of different methods (perhaps from a quantitative experiment, a survey and qualitative case studies), this will tend to justify greater confidence in the findings. For this reason, the need to make methodological choices should be seen as an asset for researchers, rather than a basis for arguments about who has the best methods. The challenge researchers face is to exploit that asset appropriately.
