data was measured and analyzed in accordance with the research questions described in chapter 1. The chapter then progresses to discuss the choice of the data analytical framework that was subsequently adopted in the study. The section concludes by comments on the ethical considerations regarding the approach adopted. 3.1 The Research Design The selected research strategy is a survey. The survey approach is the most suited method for gathering descriptive information as it involves asking participants questions on how they feel, what their views are, and what they have experienced. In a survey, the investigator examines those phenomena which exist in the universe independent of his or her action. Its advantage is that, it allowed the collection of large amounts of data from a sizeable population in a highly effective, easily and in an economical way, often using questionnaires (Saunders, Lewis, & Thornhill, 2009). This exploratory research sought to estimate the electricity potential from the municipal solid waste in Nairobi and analyzed the factors needed for a successful set up of a waste to energy facility. 3.2 Population and sampling Stratified random sampling was used to select the population. This was selected because the population to be interviewed was divided into different categories based on the stakeholder groups identified in the literature review in Figure 2-2. The identified population was categorized as shown in table 3.1. The sample size selected was 40. The respondents targeted were senior management in the respective organizations and in the case of government, the senior officers in departments responsible for the waste sector.
