Research methodology quantitative and qualitative methods

Introduction Participant observation, for many years, has been a hallmark of both anthropological and sociological studies. In recent years, the field of education has seen an increase in the number of qualitative studies that include participant observation as a way to collect information. Qualitative methods of data collection, such as interviewing, observation, and document analysis, have been included under the umbrella term of "ethnographic methods" in recent years.

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.

Sampling[ edit ] Typically a population is very large, making a census or a complete enumeration of all the values in that population infeasible. In positivist research, statistics derived from a sample are analysed in order to draw inferences regarding the population as a whole.

Quantitative Research

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. It should never lead Research methodology quantitative and qualitative methods 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.

Conclusion. A trend for conducting parallel data analysis on quantitative and qualitative data in mixed methods healthcare research has been identified in the studies included in this review. Triangulation in Social Research: Qualitative and Quantitative Methods Can Really Be Mixed 1. Triangulation In social science triangulation is defined as the mixing of data or methods so that. Conclusion. A trend for conducting parallel data analysis on quantitative and qualitative data in mixed methods healthcare research has .

Propositions are conclusions drawn about the relationships among concepts, based on analysis of axioms. Hypotheses are specified expectations about empirical reality derived from propositions.

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. The first rule is that "There should be the possibility of surprise in social research. Rule 4 advises researchers to replicate, that is, "to see if identical analyses yield similar results for different samples of people" p.

The next two rules urge researchers to "compare like with like" Rule 5 and to "study change" Rule 6 ; these two rules are especially important when researchers want to estimate the effect of one variable on another e.

The final rule, "Let method be the servant, not the master," reminds researchers that methods are the means, not the end, of social research; it is critical from the outset to fit the research design to the research issue, rather than the other way around.

Explanations in social theories can be idiographic or nomothetic.Quantitative Methods Methods include focus groups, in-depth interviews, and reviews of documents for types of themes Surveys, structured interviews & observations, and reviews of records or documents for numeric information.

My special thanks goes to Camilo Tabinas for suggesting that the difference between quantitative and qualitative research method stems from the roots of quantity and quality.

Qualitative data collection methods emerged after it has become known that traditional quantitative data collection methods were unable to express human feelings and emotions.

Monette et al () [1] credit qualitative methods with the acknowledgement of abstraction and generalisation. Properly used, "mixed methods" research is a design methodology, a paradigm, and not just an arbitrary mix of qualitative and quantitative techniques.

Main differences between quantitative and qualitative methods. The most popular quantitative data collection methods are closed-ended questionnaires, experiments, correlation and regression analysis methods and others.
