Given the complexity of research-researchers, particularly novice researchers often perplexed to make research methodology choice. A choice which can have a profound effect upon the way a research is designed and the outcome of the research. Literature on research methodologies is voluminous, however, there has been little effort to discuss the three main research methodologies in a single manuscript. Grounded in an extensive literature review this paper discusses quantitative, qualitative and mixed research methodologies, and highlights the pros and cons of each methodology. The attributes of each research methodology are also discussed.
