Quantitative research is the numerical representation and manipulation of observations for the purpose of describing and explaining the phenomena that those observations reflect. Descriptive research design is a valid method for researching specific subjects and as a precursor to more quantitative studies whilst there are some valid concerns about the statistical validity , as long as the limitations are understood by the researcher, this type of study is an invaluable scientific tool. Descriptive research is an innovative tool for researchers as it presents an opportunity to fuse both quantitative and qualitative data as a means to reconstruct the “what is” of a topic however, descriptive research also has specific advantages and disadvantages a skilled researcher can. Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies, but instead it can utilize elements of both, often within the same study the term descriptive research refers to the type of research question, design, and data analysis that will be applied to a given topic.
A traditional research design is a blueprint or detailed plan of how a research study is to be completed operating variables for measurement, selecting a sample, collecting data and analysing the results of interest to the study, and testing the hypotheses (thyer. Statement of purpose—what was studied and why ♦ description of the methodology (experimental group, control group, variables, test conditions, test subjects, etc) ♦ results (usually numeric in form presented in tables or graphs, often with statistical analysis) ♦ conclusions drawn from the results ♦ footnotes, a bibliography, author credentials. Advantages quantitative research design is an excellent way of finalizing results and proving or disproving a hypothesis the structure has not changed for centuries, so is standard across many scientific fields and disciplines.
Clearinghouse for labor operational guidelines for quantitative descriptive studies evaluation and research july 31, 2014 study design, methods, and findings, with enough information on the quality of the study and its guidelines for reviewing quantitative descriptive studies. Descriptive research is a study designed to depict the participants in an accurate way more simply put, descriptive research is all about describing people who take part in the study. Case study research has a long history within the natural sciences, social sciences, and humanities, dating back to the early 1920's at first it was a usefu.
Experimental design is the type of research design where the researcher has the ability to manipulate the predictor variable and create a cause and effect relationship. Quantitative research falls into four main designs, namely, descriptive, correlational, experimental and quasi‑ experimental (borbasi and jackson 2012 burns and grove 2009) the main aim of descriptive research. Descriptive research can be explained as a statement of affairs as they are at present with the researcher having no control over variable moreover, “descriptive studies may be characterised as simply the attempt to determine, describe or identify what is, while analytical research attempts to. The research design for this study is a descriptive and interpretive case study that is analysed through qualitative methods questionnaires were used to evaluate.
What is correlational research unlike in the case of descriptive research where the focus is on collecting descriptive data, in correlational research the researcher attempts to identify associations that exist between variables the researcher also makes an effort to understand the nature of the relationship as well. Descriptive statistics are used to describe the basic features of the data in a study they provide simple summaries about the sample and the measures together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data. Chapter 3 research design and method 31 introduction in this chapter the researcher explains how the research study was conducted a quantitative, descriptive study was conducted to determine: when very little is known about a topic or to explore a research question, a descriptive design is applied within the context of this research, the. Quantitative descriptive analysis (qda) is a registered trademark with the united states patent and trademark office the term was coined by herbert stone (a food scientist) and joel l sidel (a psychologist)  in 1974 while at the stanford research institute, (now known as sri international (sri) . Descriptive designs typically are an eclectic but reasonable combination of sampling, and data collection, analysis, and re-presentation techniques qualitative descriptive study is the method of choice when straight descrip.
There is a potentially infinite array of possible quantitative research designs, and in the human sciences particularly, it can be difficult to do pure, experimental research thus a great many adaptations of experimental designs, called quasi-experimental and non-experimental designs have been developed. Some research studies use mixed designs, so more than one design can be chosen a mixed method approach, that is using both a quantitative and qualitative design, may also be. We do descriptive qualitative research designin most cases, we decide when to do the descriptive research instead of letting our clients decide for us this type of research refers to the type of research question, design and data analysis that will be applied to a given topic.
The information is treated in a quantitative manner, basing the design of research on a sample that gives answers generalizable to a reference population (or market segment) descriptive. Descriptive research although some people dismiss descriptive research as ‘mere descrip- tion’, good description is fundamental to the research enterprise and it. In quantitative research, designs can be classified into one of three categories: descriptive non-experimental, quasi-experimental or experimental to identify which of these designs your study is.
Types of quantitative research question dissertations that are based on a quantitative research design attempt to answer at least one quantitative research questionin some cases, these quantitative research questions will be followed by either research hypotheses or null hypotheseshowever, this article focuses solely on quantitative research questions. The design can be used with both quantitative and qualitative methods rember that because of the differences between qualitative and quantitative research in philosophy, and the order in which steps are taken, the two studies would be very different. Research design can be divided into two groups: exploratory and conclusive some authors consider research design as the choice between qualitative and quantitative research methods descriptive research design, as the name suggests, describes specific elements, causes, or phenomena in the research area. Research design is also based on the nature of the research problem or issue being addressed, the researchers’ personal experiences, and the audiences for the study the three types of designs quantitative research, for example, starts with the test of a theory 3 data, evidence, and rational considerations shape knowledge.
