Natural sciences and social sciences, quantitative research is the systematic empirical investigation of observable phenomena via statistical, mathematical or computational techniques. 1] the objective of quantitative research is to develop and employ mathematical models, theories and hypotheses pertaining to phenomena.
The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships. Quantitative data is any data that is in numerical form such as statistics, percentages, etc. 1] the researcher analyses the data with the help of statistics and hopes the numbers will yield an unbiased result that can be generalized to some larger population. Qualitative research, on the other hand, inquires deeply into specific experiences, with the intention of describing and exploring meaning through text, narrative, or visual-based data, by developing themes exclusive to that set of participants. Social sciences, quantitative research is widely used in psychology, economics, demography, sociology, marketing, community health, health & human development, gender and political science, and less frequently in anthropology and history. Research in mathematical sciences such as physics is also 'quantitative' by definition, though this use of the term differs in context.
In the social sciences, the term relates to empirical methods, originating in both philosophical positivism and the history of statistics, which contrast with qualitative research ative research produces information only on the particular cases studied, and any more general conclusions are only hypotheses. Comprehensive analysis of 1274 articles published in the top two american sociology journals between 1935 and 2005 found that roughly two thirds of these articles used quantitative method. Relationship with qualitative tative research is generally made using scientific methods, which can include:The generation of models, theories and development of instruments and methods for mental control and manipulation of tion of empirical ng and analysis of tative research is often contrasted with qualitative research, which is the examination, analysis and interpretation of observations for the purpose of discovering underlying meanings and patterns of relationships, including classifications of types of phenomena and entities, in a manner that does not involve mathematical models. 4] approaches to quantitative psychology were first modeled on quantitative approaches in the physical sciences by gustav fechner in his work on psychophysics, which built on the work of ernst heinrich weber. Although a distinction is commonly drawn between qualitative and quantitative aspects of scientific investigation, it has been argued that the two go hand in hand. 5] qualitative research is often used to gain a general sense of phenomena and to form theories that can be tested using further quantitative research.
For instance, in the social sciences qualitative research methods are often used to gain better understanding of such things as intentionality (from the speech response of the researchee) and meaning (why did this person/group say something and what did it mean to them? Quantitative investigation of the world has existed since people first began to record events or objects that had been counted, the modern idea of quantitative processes have their roots in auguste comte's positivist framework. Is the most widely used branch of mathematics in quantitative research outside of the physical sciences, and also finds applications within the physical sciences, such as in statistical mechanics. Quantitative research using statistical methods starts with the collection of data, based on the hypothesis or theory. In the field of health, for example, researchers might measure and study the relationship between dietary intake and measurable physiological effects such as weight loss, controlling for other key variables such as exercise. Quantitatively based opinion surveys are widely used in the media, with statistics such as the proportion of respondents in favor of a position commonly reported.
In the field of climate science, researchers compile and compare statistics such as temperature or atmospheric concentrations of carbon cal relationships and associations are also frequently studied by using some form of general linear model, non-linear model, or by using factor analysis. A fundamental principle in quantitative research is that correlation does not imply causation, although some such as clive granger suggest that a series of correlations can imply a degree of causality. Associations may be examined between any combination of continuous and categorical variables using methods of regarding the role of measurement in quantitative research are somewhat divergent. However, it has been argued that measurement often plays a more important role in quantitative research. 9] for example, kuhn argued that within quantitative research, the results that are shown can prove to be strange. This is because accepting a theory based on results of quantitative data could prove to be a natural phenomenon.
He argued that such abnormalities are interesting when done during the process of obtaining data, as seen below:When measurement departs from theory, it is likely to yield mere numbers, and their very neutrality makes them particularly sterile as a source of remedial suggestions. But numbers register the departure from theory with an authority and finesse that no qualitative technique can duplicate, and that departure is often enough to start a search (kuhn, 1961, p. In contrast, probabilistic measurement models known as the rasch model and item response theory models are generally employed in the social sciences. Psychometrics is the field of study concerned with the theory and technique for measuring social and psychological attributes and phenomena. This field is central to much quantitative research that is undertaken within the social tative research may involve the use of proxies as stand-ins for other quantities that cannot be directly measured. Although scientists cannot directly measure the temperature of past years, tree-ring width and other climate proxies have been used to provide a semi-quantitative record of average temperature in the northern hemisphere back to 1000 a.
Most physical and biological sciences, the use of either quantitative or qualitative methods is uncontroversial, and each is used when appropriate. Qualitative methods might be used to understand the meaning of the conclusions produced by quantitative methods. Using quantitative methods, it is possible to give precise and testable expression to qualitative ideas. This combination of quantitative and qualitative data gathering is often referred to as mixed-methods research.

A non-profit us: 727-442-4290blogabout | academic solutions | academic research resources | dissertation resources | theoretical tical theoretical framework is presented in the early section of a dissertation and provides the rationale for conducting your research to investigate a particular research er the theoretical framework as a conceptual model that establishes a sense of structure that guides your research. It provides the background that supports your investigation and offers the reader a justification for your study of a particular research problem. Essentially, this is where you describe a “theory” and build your case for investigating that theory. Theoretical framework is a summary of your theory regarding a particular problem that is developed through a review of previous research on the variables involved. Development of the theoretical framework helps to clarify your implicit theory in a manner that is more clearly defined.
You will also consider the limitations associated with your theory, and quite possibly, that your problem could be better understood by other theoretical theoretical framework is how you conceptualize the nature of your research problem, its basis and the analysis you will choose to investigate that problem. The theoretical framework allows you to present the research problem in light of a summary of the description of the variables of interest in context of the literature review allows the reader to understand the theorized relationships. You will investigate other researchers’ theories behind these relationships and identify a theory (or combination of theories) that explains your major research problem. Essentially, your goal is to convey to the reader why you think your variables are related, so the inclusion of previous research and theories that support your belief are essential to defending your rationale. You apply the theory to your problem, and state your hypotheses or predictions regarding potential relationships. You tell the reader what you expect to find in your does theoretical framework relate to quantitative research design?
The choice of research design is based on the goals of the study and a solid review of the literature. Quantitative research design utilizes deductive reasoning, which begins with identifying the theoretical framework that will provide structure and guide the research project. The theoretical framework is presented in the early sections of a quantitative research proposal to establish the grounds for the theoretical framework will direct the research methods you choose to employ. The theoretical framework involves a discussion of (1) the research problem and (2) the rationale for conducting an investigation of the problem. These two factors form the basis of a theoretical framework section of the research onal webpages related to theoretical s section: chapter s section: chapter ting qualitative research and ch concept ptive statistics and interpreting ell, g. In empirical research we are not only interested in variations in our data (what we observe happening in the world), but we also want to test whether the data fits to our model or a theory.
The first, in which researchers formulate hypotheses on the basis of the previous research and test them against empirical data, is called confirmatory research. This method starts with the data and exploring in order to formulate hypotheses and theories based on the understanding derived from the data analyzers may suggest that exploratory data analysis could be followed by confirmatory analysis: first the researcher explores the data, finds some interesting associations, then finds theory to support the observed variations, and finally performs a statistical test to verify what has just been found. In theory, one can find arbitrary evidence from the data and develop a theory around it to “confirm” the observations. Confirmation bias can be harmful in scientific research, and statistical methods are exactly the way of avoiding succumbing to it. Therefore, good scientific research is based on some type of theoretical reasoning, either taken as given and tested against empirical data or developed over the course of data exploration and carefully linked with an existing body of empirical research and ted: group projects to chooose you analysis method?
