Why research methodology

Causation: related to some of the earlier things I talked about, confounding variables are variables other than the identified dependent and independent variables that come into play and affect the results.The examples and perspective in this section may not represent a worldwide view of the subject.

Qualitative Methods in Educational and Social Research

The Education Dissertation A Guide for Practitioner Scholars.We might conclude that old age thus results in less lung capacity.

There are two main groups of research methods in the social sciences.There are far too many individuals who do not make it into the mental health system to even be identified as depressed, let alone to test their CSF.Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences.Thus, it is possible that the increased number of receptors on the postsynaptic neuron is actually responsible for the relationship between neurotransmitter levels and depression.These experiments ranged from Kirlian photography to try to get pictures of phantom limbs, to using EEG to measure any neurological abnormalities in Otherkin compared to the general population.This paper explores the most common methods of data collection used in qualitative research: interviews and focus groups.Research is a careful and detailed study into a specific problem, concern, or issue using the scientific method.

T his discussion includes describing the theoretical concepts that inform the choice of methods to be applied, placing the choice of methods within the more general nature of academic work, and reviewing its relevance to examining the research problem.These include observational research, correlational research, true experiments, and quasi-experiments.The United States government spends millions of dollars to conduct the U.S. Census every ten years.Now that we have these terms defined, we can examine further the structure of the true experiment.Describe how you plan to obtain an accurate assessment of relationships, patterns, trends, distributions, and possible contradictions found in the data.In experimental work, it typically involves direct or indirect observation of the researched subject(s), e.g., in the laboratory or in the field, documents the methodology, results, and conclusions of an experiment or set of experiments, or offers a novel interpretation of previous results.Upper Saddle River, NJ: Prentice Hall. 2008 ISBN 0-13-613550-1 (pages 8-9).I have a presentation next week, and I am at the search for such information.Research design provides the glue that holds the research project together.

If we were to conduct the quasi-experiment, we would find that the older group had less lung capacity as compared to the younger group.Learn more about determining the research design in the Boundless open textbook.The reverse approach is justified by the transactional nature of the research endeavor where research inquiry, research questions, research method, relevant research literature, and so on are not fully known until the findings have fully emerged and been interpreted.Remember that you are not writing a how-to guide about a particular method.Research ethics is most developed as a concept in medical research.The dependent variable consisted of the heart rates, fluid intake, and anxiety measures.Many senior researchers (such as group leaders) spend a significant amount of their time applying for grants for research funds.

A clinical trial is defined as a carefully designed experiment that seeks to determine the clinical efficacy of a new treatment or drug.Once you have written all of the elements of the methods section, subsequent revisions should focus on how to present those elements as clearly and as logically as possibly.In a stratified sample, we sample either proportionately or equally to represent various strata or subpopulations.Thus, we must be careful concerning making statement of causality with quasi-experimental designs.Help About Wikipedia Community portal Recent changes Contact page.Non-empirical ( theoretical ) research is an approach that involves the development of theory as opposed to using observation and experimentation.A. Importance of Research Methodology in Research Study It is necessary for a researcher to design a methodology for the problem chosen.

A key concept relevant to a discussion of research methodology is that of validity.This, however, does not mean that new ideas and innovations cannot be found within the pool of existing and established knowledge.In this sense, a hypothesis can never be proven, but rather only supported by surviving rounds of scientific testing and, eventually, becoming widely thought of as true.A systematic sample is conducted by randomly selecting a first case on a list of the population and then proceeding every Nth case until your sample is selected.A design is used to structure the research, to show how all of the major parts of the.Children were randomly assigned to either the treatment or the control condition.If that measure does not truly reflect depression levels but rather anxiety levels (Confounding Variable X), than my study will be lacking construct validity.


A research study is a scientific way to improve or develop new methods of health care.Are you constructing your experiments with a large enough sample to make a statistical difference.Thus, good construct validity means the we will be relatively sure that Construct A is related to Construct B and that this is possibly a causal relationship.A qualitative approach, such as conducting interviews or content analysis of archival texts, can yield exciting new insights about a research problem, but it should not be undertaken simply because you have a disdain for running a simple regression.

In publishing, STM publishing is an abbreviation for academic publications in science, technology, and medicine.Main page Contents Featured content Current events Random article Donate to Wikipedia Wikipedia store.For example, if you conduct a study looking at heart disease in men, can these results be generalized to women.Your methods should have a clear connection with your research problem.
