Sampling methods in qualitative research

It describes, either explicitly or implicitly, the purpose of the qualitative research, the role of the researcher sthe stages of research, and the method of data analysis. Ethnography The ethnographic approach to qualitative research comes largely from the field of anthropology. The emphasis in ethnography is on studying an entire culture. Originally, the idea of a culture was tied to the notion of ethnicity and geographic location e.

Method[ edit ] Social scientists are divided into camps of support for particular research techniques. These disputes relate to the historical core of social theory positivism and antipositivism ; structure and agency. 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.

Ethnography

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 triangulatequantitative 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. 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.

Phenomenology

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 individualsnot 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 phenomenonand 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. Axioms or postulates are basic assertions assumed to be true. Propositions are conclusions drawn about the relationships among concepts, based on analysis of axioms.

Hypotheses are specified expectations about empirical reality derived from propositions.

The methods most commonly used in qualitative studies are given here, including the purpose for which the method is especially useful and its disadvantages. Convenience sampling Many health facility or drug-outlet-based studies use convenience samples. Social research is a research conducted by social scientists following a systematic plan. Social research methodologies can be classified as quantitative and qualitative.. Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable. A qualitative "approach" is a general way of thinking about conducting qualitative research. It describes, either explicitly or implicitly, the purpose of the qualitative research, the role of the researcher(s), the stages of research, and the method of data analysis. here, four of the major qualitative approaches are introduced.

Social research involves testing these hypotheses to see if they are true. Social research involves creating a theory, operationalization measurement of variables and observation actual collection of data to test hypothesized relationship.

Social theories are written in the language of variables, in other words, theories describe logical relationships between variables. Variables are logical sets of attributes, with people being the "carriers" of those variables for example, gender can be a variable with two attributes: Variables are also divided into independent variables data that influences the dependent variables which scientists are trying to explain.

For example, in a study of how different dosages of a drug are related to the severity of symptoms of a disease, a measure of the severity of the symptoms of the disease is a dependent variable and the administration of the drug in specified doses is the independent variable.

Researchers will compare the different values of the dependent variable severity of the symptoms and attempt to draw conclusions. Guidelines for "good research"[ edit ] When social scientists speak of "good research" the guidelines refer to how the science is mentioned and understood.

It does not refer to how what the results are but how they are figured. Glenn Firebaugh summarizes the principles for good research in his book Seven Rules for Social Research.Qualitative Research Methods from University of Amsterdam.

Qualitative: Quantitative: Definitions: a systematic subjective approach used to describe life experiences and give them meaning: a formal, objective, systematic process for obtaining information about the world.

Sampling for qualitative research Martin N Marshall Marshall, MN. Sampling for qualitative research. both quantitative and qualitative methods of sampling The choice between quantitative and qualitative research methods should be determined by the research ques-tion, not by the preference of the researcher.

It would. There are a wide variety of methods that are common in qualitative measurement. In fact, the methods are largely limited by the imagination of the researcher.
