Students of research (and even practitioners) more often than not confuse between research designs and research approaches. According to Kothari (2004), research design is a plan, a roadmap and blueprint strategy of investigation conceived so as to obtain answers to research questions (Kothari, 2004), it is the heart of any study. Research design constitutes the blueprint or the roadmap for the collection, measurement, and analysis of data. This is done in order to ensure that one effectively addresses the research problem. The research design refers to the overall strategy that one may choose to integrate the different components of the study in a coherent and logical way. Research methodology encompasses concepts such as research designs, target population, sample size and sampling procedure, data collection instruments and data analysis procedure. A Methodology does not set out to provide solutions but offers the theoretical underpinning for understanding which procedure, set of procedures can be applied to a specific case. It involves procedures of describing, explaining and predicting phenomena so as to solve a problem it is the ‘hows’ the process or techniques of conducting research. The research methodology is the systematic, theoretical analysis of the procedures applied to a field of study (Kothari, 2004).
