Learning Objectives Distinguish between quantitative and qualitative research methods. Identify whether or research project is qualitative or quantitative in nature. List the key factors that must be considered when choosing a research design. Quantitative and Qualitative Designs There are two main approaches to a research problem - quantitative and qualitative methods. Choosing a Design The following table lists and describes the most common research designs used at Grand Canyon University.
Case Study And Historical Intent is to study and understand a single situation, which could be a leader, a classroom, a process, program, activity. Causal Comparative Compare two groups with the intent of understanding the reasons or causes for the two groups being different. Narrative Describe the lives of individual s to get meaning from them. Experimental Test an idea, treatment, program to see if it makes a difference.
Quasi-experimental It is the same as experiment in that there is a control and test group. Phenomenology Studies a human experience at an experiential level such as understanding what it means for a woman to lose a child.
Mixed Research Designs A mixed research design involves having both a quantitative design and qualitative design. Research Tutorials Why Research?

Research Design Research design involves determining how your chosen method will be applied to answer your research question. Relationship Choice of research methods and design should be thought of as a reciprocal process extending well into your study.

Accessed 14 September 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.
Research design can be divided into two groups: exploratory and conclusive. Exploratory research, according to its name merely aims to explore specific.
CHAPTER 4 Research Methodology and Design Introduction All research is based on some underlying philosophical assumptions about what constitutes 'valid' research and which research method(s) is/are appropriate for the.
WHAT IS RESEARCH DESIGN? 1 THE CONTEXT OF DESIGN Before examining types of research designs it is important to be clear 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 methods design. 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.
Research Design and Research Methods CHAPTER 3 This chapter uses an emphasis on research design to discuss qualitative, quantitative, and mixed methods research as three major approaches to. 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.
