If research and theory are inextricably linked, then one cannot understand the ‎nature of theory without first understanding the nature of research. There are two types ‎of research design in the scientific inquiry - qualitative and quantitative. Qualitative and ‎quantitative research designs are the basis of the scholarly study utilized regarding the ‎purpose of the research and recourses available for investigation. There are situations ‎when researchers apply both types of design, as in cases when it is important to enhance ‎internal and external validity, credibility, and reliability of the results. Both qualitative ‎and quantitative designs have advantages and disadvantages that can either benefit the ‎study or jeopardize the research if implemented incorrectly. Additionally, both research ‎designs contribute to theory differently. ‎
The quantitative research design is implemented when the researcher aims to ‎analyze collected data with the help of statistical tools. It is important to mention that ‎this research design is the most prevalent among scientists. Quantitative research design ‎applies in case of different studies relying exclusively on information collected during ‎the experiments and surveys (Duffy & Chenail, 2008). The distinguishing feature of ‎quantitative research is its ability to analyze the relationship between variables. Yet, it ‎does not explain why a phenomenon or event happened. ‎
The aim of the quantitative approach is to reveal the relationship between the ‎variables and to test a particular hypothesis. Quantitative research design can contribute ‎to theory by detecting the connections or lack thereof between variables. The purpose of ‎quantitative design is to prove or disapprove a hypothesis. Such ...

...implemented incorrectly. A mixed methods design includes both qualitative and ‎quantitative designs, and has the ability to enhance internal and external validity, ‎credibility, and reliability of the results. ‎
‎ ‎ Regardless of the method chosen, research often advances theory in multiple ‎ways. Research can test theory, identify relationships between variables, or provide ‎additional meaning (Ellis & Levy, 2008; Anders, 2009). One of the main constructs of ‎both theory is that it advances the body of knowledge. Therefore appropriate research ‎should advance theory. It should answer a question or help solve a problem. Research ‎should open a new dialogue with the current understanding of a theory within a field. ‎Inherent researcher bias or failure to identify all the things not researched can severely ‎limit the expansion of new knowledge (Anders, 2009). ‎

Questions On Qualitative And Quantitative Research Essay

- Introduction To respond to this question the author concurs that qualitative and quantitative research are different in many fundamental ways (Abowitz & Toole, 2010) ranging from properties, collection and use of data collections methods, ways to analyse data to advantages and disadvantages (Zawawi, 2007; Saunders et al., 2009). The paper will analyse differences along philosophical lines taking into account some of the ongoing philosophical debates in social sciences (Weber, 2004) through to data collection and possibly data analysis (Smith et al., 91; Crotty, 98; Onwuegbeu et al, 2006)....   [tags: Qualitative research, Scientific method]

Essay on Designing Social Inquiry : Scientific Inference

- King, Keohane, and Verba (1994) in “Designing Social Inquiry: Scientific Inference in Qualitative Research” attempt to unify political science under a single logic of inquiry based on quantitative regression analysis. While initially divisive even somewhat offensive to qualitative scholars, this debate culminated in greater scrutiny of qualitative methods and the delineation of the key advantages and limitations of both qualitative and quantitative methods. In the end, KKV’s attempt to unite the field provided an opportunity for advances and expansions in both quantitative and qualitative methodologies, greatly expanding and enhancing the comparativist’s methodological toolbox....   [tags: Qualitative research, Scientific method]

Types Of Qualitative And Qualitative Research Essay

- Types of Qualitative Methods When a qualitative approach seems to make the most sense, the task becomes one of selecting the qualitative method or methods to be used. A number of different ways of framing qualitative methods exist. Lee, Mitchell, and Sablynski (1999) use purposes (e.g., theory generation, theory elaboration, theory testing, or critical theory), research design (e.g., case study, ethnography, and in-depth interviews), and analytic data techniques (e.g., grounded theory approaches, pattern matching in case study research, and hermeneutic techniques as a way of categorizing types of qualitative research....   [tags: Qualitative research, Scientific method]

Qualitative Study On Qualitative Research Essay

- Qualitative Study Design Chart From a distinctive case study to an all-encompassing interview, the talent to analyze the nature of a phenomenon utilizing qualitative research designs is established upon in-depth analysis by the researcher (Bryman, 2006). Case studies, observations, interviews, and survey designs are the most frequently exploited approaches (Ukiwe, 2011). The objective of this research is to create a chart listing the various designs one may consider for a qualitative study along with the type of data collection....   [tags: Qualitative research, Scientific method]

Using Qualitative And Quantitative Methods For The Research Design Essay

- There is a variety of research designs available for researchers to choose. However, it is essential that researchers choose the most appropriate research design for their study. Consequently, the research design is chosen from three categories of methods that include quantitative, qualitative, and mixed (Creswell, 2014). The purpose of this paper is to formulate two hypothetical research designs using qualitative and quantitative methods for the intended research topic. Quantitative Method: Survey Research Design The first hypothetical research design selected is survey research....   [tags: Scientific method, Qualitative research]

Essay about The Nature and Limitations of Scientific Enquiry

- The practice of science should always be undertaken with precautions to guard against against one's own prejudices. In scientific inquiry, the search for an absolute, objective truth is not obtainable since the interpretation of empirical data is based on factors more that the data itself: science relies on shaping principles which are as varied as there are scientists. This means that two scientists looking at the same data are likely to come up with different theories based on the philosophical, personal or even societal non-empirical inclinations which determine how they interpret data....   [tags: scientific method, scientific inquiry, scientists]
