Qualitative research often categorizes data into patterns as the primary basis for organizing and reporting results. Qualitative research typically rely on the following methods of gathering information: participant observation, non-participant observation, notes, journals, books, analysis of documents and materials, interviews. Qualitative researchers may use different approaches in collecting data, such as the grounded theory practice, narratology, storytelling, classical ethnography, or shadowing. Grounded Theory, is an inductive type of research, based or “grounded” in the observations or data from which it was developed; it uses a variety of data sources, including quantitative data, review of records, interviews, observation and surveys. My research is a grounded theory qualitative research in which I’ve used quantitative data also. Mainly for representing the Randomized Controlled Trials RCTs) and the chapters presenting Flu d, l tr lyt nd m n r l rturb t n .A randomized controlled trial (RCT) is a type of scientific experiment most commonly used in testing the efficacy or effectiveness of healthcare services (such as medicine or nursing) or health technologies (such as pharmaceuticals, medical devices or surgery). RCTs are also employed in other research areas, such as judicial, educational, international development and social science research. As their name suggests, RCTs involve the random allocation of different interventions (treatments or conditions) to subjects. As 52 long as the numbers of subjects are sufficient, randomization is an effective method for balancing confounding factors between treatment groups. Randomized controlled trials (RCT) are currently being used by a number of international development experts to measure the impact of development interventions worldwide. Development economists at a number of research organizations including Poverty Action Lab and Innovations for Poverty Action (IPA) have used RCTs to measure the effectiveness of poverty and health programs in the developing world. Randomized controlled trials can be highly effective in policy evaluation since they allow researchers to isolate the impacts of a specific program from other factors such as: other programs offered in the region, general macroeconomic growth, and short-term events such as a favorable harvest. Randomized Controlled Trials also help control for differences in personal qualities that might make one individual more successful than another. By identifying a group of participants and separating them randomly into otherwise similar control and treatment groups, randomized trials allow researchers to reliably conclude whether a particular program is responsible for generating positive changes in income, health, education, or other poverty-related areas. For development economists, the main benefit to using randomized controlled trials compared to other research methods is that randomization guards against selection bias, a problem present in many current studies of development policy. Methodology can be defined as: • "the analysis of the principles of methods, rules, and postulates employed by a discipline";¨ • "the systematic study of methods that are, can be, or have been applied within a discipline";or "a particular procedure or set of procedures."
