Research Methodology Books
While very different in many aspects, both qualitative and quantitative approaches involve a systematic interaction between theory and data.
For example, a researcher concerned with drawing a statistical generalization across an entire population may administer a survey questionnaire to a representative sample population. By contrast, a researcher who seeks full contextual understanding of an individuals' social actions may choose ethnographic participant observation or open-ended interviews. Studies will commonly combine, or triangulate , quantitative and qualitative methods as part of a multi-strategy design.
Sampling[ edit ] Typically a population is very large, making a census or a complete enumeration of all the values in that population infeasible. A sample thus forms a manageable subset of a population. In positivist research, statistics derived from a sample are analysed in order to draw inferences regarding the population as a whole. The process of collecting information from a sample is referred to as sampling.
Sampling is quicker and cheaper than a complete census of a population. Methodological assumptions[ edit ] Social research is based on logic and empirical observations. Charles C. Ragin writes in his Constructing Social Research book that "Social research involved the interaction between ideas and evidence.
Ideas help social researchers make sense of evidence, and researchers use evidence to extend, revise and test ideas.
It should never lead or be mistaken with philosophy or belief. Social research aims to find social patterns of regularity in social life and usually deals with social groups aggregates of individuals , not individuals themselves although science of psychology is an exception here. Research can also be divided into pure research and applied research. Pure research has no application on real life, whereas applied research attempts to influence the real world. There are no laws in social science that parallel the laws in natural science.
A law in social science is a universal generalization about a class of facts. A fact is an observed phenomenon , and observation means it has been seen, heard or otherwise experienced by researcher. A theory is a systematic explanation for the observations that relate to a particular aspect of social life. Concepts are the basic building blocks of theory and are abstract elements representing classes of phenomena. The codes are then summarized into similar concepts in order to make the extensive text data more comprehensible.
From the concepts, categories are formed.
This is how a study was analyzed, where qualitative data collection was conducted to study factors affecting the implementation of a randomized controlled trial parallel to the trial's quantitative assessment of the effectiveness of a transitional discharge model for people with a serious mental illness.
Inductive logic is then used to arrive at a theory or general principles from the categories revealed by the data. The inadequacies of deduction and induction logic are well-known. While deduction can give absolute proof, it really does not make contact with the real social world, there is no way to test the validity of the premises.

Induction though is driven by data, but it also cannot provide proof of a theory in a strict sense. Triangulation is often used to check whether different methods lead to same results when two or more methods are used to study the same phenomenon. It acts as an alternative to traditional concepts of reliability and validity. By combining multiple observers, theories, methods, and empirical materials; researchers can hope to overcome the weakness or intrinsic biases and the problems that come from single method, single observer, and single theory studies.
Public Health Relevance Public health has moved through the four developmental phases, namely environmental, individualistic, therapeutic, and new public health.
Therefore, there is a need for understanding public health holistically while keeping the users of public health in the center. These issues need to be reexplored using research methods that can complement each other.
The health systems are not only debating the alternatives like Health in All Policies to address the social determinants of health but are also exploring how to make health services more equitable. However, generally provider's perspective is used in defining the concepts of availability, accessibility, and affordability; which have been used rather loosely in the facility surveys or household surveys to identify gaps in infrastructure, equipment, human resources, services coverage, etc.
This approach often fails to assess the felt needs of the health service users. In the recent past, public health has witnessed a paradigm shift from only delivering the interventions to understanding the health behavior of people, especially to prioritize options on how the risk behaviors can be addressed to reduce harm.
Putting the knowledge into practice or translational or implementation research to enhance health equity, that is, reducing health status differences between and within population groups, is another area where mixed method research can lead to formulation of policies that enhance access to effective care by provision of user-friendly public health services to those who need it most.
Conclusions Public health deals with several complex situations from formulation of policies to delivery of interventions. Hence, a comprehensive understanding of the functioning of the society is required. Mixed method approach helps in having a more comprehensive understanding of the structure and functioning of society at large.
Mixed method research intentionally integrates quantitative and qualitative methods rigorously to draw on the strengths of each other to ensure that the results of a study are more close to reality.
Hence, public health researchers need to have a good understanding of the mixed method approach including its philosophical underpinnings for exploring the complex situations that confront public health today.

Qual Rep.There are a list of questions that a researcher intends to ask which need to be customized according to the target market. There is often a paucity of baseline data, poor facilities for marketing research e. Such teams are intended to be comprised of some members with relevant technical backgrounds and others with social science skills, including marketing research skills.
With the idea of RRA in mind, he is "convinced that the same message could have been put across more quickly, cheaply and effectively, with evidence drawn from a smaller, purposively selected and studied sample and with no significant reduction in reliability". The size of the sample varies with the research questions and research design. It cannot be accomplished simply by driving along a main road looking at fields although such a method may be a way to begin.
Laboratory and field experiments are preferred by researchers.
