Research Methods vs Research Design. In a research project, two significant elements between that certain differences can be identified are the research design and methods.

Hence, for those pursuing research in any field of study, an awareness of research methods and research design is vital. There are many research methods that provide a loose framework or guidelines to conduct a research project. One has to choose a method that suits the requirements of the project, and the researcher is comfortable with. On the other hand, the research design is the specific framework within which a project is pursued and completed. Many remain confused about the differences between research methods and research design.

This article will differentiate between the two and make it easier for research students. This is before looking at the statistics required, and studying the preferred methods for the individual scientific discipline. Every experimental design must make compromises and generalizations , so the researcher must try to minimize these, whilst remaining realistic.

For biology, psychology and social sciences, there can be a huge variety of methods to choose from, and a researcher will have to justify their choice. The first method is the straightforward experiment, involving the standard practice of manipulating quantitative, independent variables to generate statistically analyzable data.

Generally, the system of scientific measurements is interval or ratio based. The researcher is accepting or refuting the null hypothesis. The results generated are analyzable and are used to test hypotheses , with statistics giving a clear and unambiguous picture. This research method is one of the most difficult, requiring rigorous design and a great deal of expense, especially for larger experiments.

The other problem, where real life organisms are used, is that taking something out of its natural environment can seriously affect its behavior. It is also the biggest drain on time and resources, and is often impossible to perform for some fields, because of ethical considerations. The Tuskegee Syphilis Study was a prime example of experimental research that was fixated on results, and failed to take into account moral considerations.

In other fields of study, which do not always have the luxury of definable and quantifiable variables - you need to use different research methods. These should attempt to fit all of the definitions of repeatability or falsifiability , although this is not always feasible. Opinion based research methods generally involve designing an experiment and collecting quantitative data. For this type of research, the measurements are usually arbitrary, following the ordinal or interval type.

Questionnaires are an effective way of quantifying data from a sample group, and testing emotions or preferences. This method is very cheap and easy, where budget is a problem, and gives an element of scale to opinion and emotion.

These figures are arbitrary, but at least give a directional method of measuring intensity. By definition, this experiment method must be used where emotions or behaviors are measured, as there is no other way of defining the variables.

Whilst not as robust as experimental research , the methods can be replicated and the results falsified. Design Research emerged as a recognisable field of study in the s, initially marked by a conference on Design methods [1] at Imperial College London , in The Design Research Society has always stated its aim as: Its purpose therefore is to act as a form of learned society , taking a scholarly and domain independent view of the process of designing.

Some of the origins of design methods and design research lay in the emergence after the 2nd World War of operational research methods and management decision-making techniques, the development of creativity techniques in the s, and the beginnings of computer programs for problem solving in the s. A statement by Bruce Archer [3] encapsulated what was going on: Early work was mainly within the domains of architecture and industrial design , but research in engineering design developed strongly in the s; for example, through ICED—the series of International Conferences on Engineering Design, now run by The Design Society.

These developments were especially strong in Germany and Japan. In the USA there were also some important developments in design theory and methodology, including the publications of the Design Methods Group and the series of conferences of the Environmental Design Research Association. The National Science Foundation initiative on design theory and methods led to substantial growth in engineering design research in the lates.

A particularly significant development was the emergence of the first journals of design research. The development of design research has led to the establishment of design as a coherent discipline of study in its own right, based on the view that design has its own things to know and its own ways of knowing them.

The research design for this study is a descriptive and interpretive case study that is analysed through qualitative methods. Questionnaires were used to evaluate.

Others argue that research design refers to the choice of specific methods of data collection and analysis. In your dissertation you can define research design as a general plan about what you will do to answer the research question. [1].

about the role and purpose of research design. We need to understand what research design is and what it is not. We need to know where design fits into the whole research process from framing a question to finally analysing and reporting data. This is the purpose of this chapter. methods design design. THE CONTEXT OF DESIGN. Design lacks rigorous standards applied to methods of data gathering and analysis because one of the areas for exploration could be to determine what method or methodologies could best fit .

A research method is a general framework guiding a research project. Different methods can be used to tackle different questions. Research design is a specific outline detailing how your chosen method will be applied to answer a particular research question. design as “the researcher’s overall for answering the research question or testing the research hypothesis”. This study focuses on the opinion of nurses on pain in patients that suffer from dementia.
