Quantitative research

Quantitative research is the research strategy that focuses on quantifying the collection together with analysis of data. it is for formed from a deductive approach where emphasis is placed on the testing of theory, shaped by empiricist and positivist philosophies.

Associated with the natural, applied, formal, and social sciences this research strategy promotes the objective empirical investigation of observable phenomena to test and understand relationships. This is done through a range of quantifying methods and techniques, reflecting on its broad utilization as a research strategy across differing academic disciplines.

The objective of quantitative research is to introducing and employ mathematical models, theories, and hypotheses pertaining to phenomena. The process of measurement is central to quantitative research because it ensures the fundamental association between empirical observation and mathematical expression of quantitative relationships.

Quantitative data is all data that is in numerical take such as statistics, percentages, etc. The researcher analyses the data with the assist of statistics and hopes the numbers will yield an unbiased a thing that is said that can be generalized to some larger population. Qualitative research, on the other hand, inquires deeply into particular experiences, with the aim of describing and exploring meaning through text, narrative, or visual-based data, by development themes exclusive to that classification of participants.

Quantitative research is widely used in psychology, economics, demography, sociology, marketing, community health, health & human development, gender studies, 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, in contrast with qualitative research methods.

Qualitative research produces information only on the particular cases studied, and all more general conclusions are only hypotheses. Quantitative methods can be used to verify which of such(a) hypotheses are true. A 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.

Overview

Quantitative research is broadly closely affiliated with ideas from 'the scientific method', which can include:

Quantitative research is often contrasted with qualitative research, which purports to be focused more on discovering underlying meanings and patterns of relationships, including classifications of species of phenomena and entities, in a manner that does non involve mathematical models. Approaches to quantitative psychology were number one modeled on quantitative approaches in the physical sciences by Gustav Fechner in his form believe on psychophysics, which built on the work of Ernst Heinrich Weber. Although a distinction is normally drawn between qualitative and quantitative aspects of scientific investigation, it has been argued that the two go hand in hand. For example, based on analysis of the history of science, Kuhn concludes that “large amounts of qualitative work have ordinarily been prerequisites to fruitful quantification in the physical sciences”. 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 apprehension 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 intend to them?

Although quantitative investigation of the world has existed since people first began to record events or objects that had been counted, the advanced idea of quantitative processes have their roots in Auguste Comte's positivist framework. Positivism emphasized the usage of the scientific method through observation to empirically test hypotheses explaining and predicting what, where, why, how, and when phenomena occurred. Positivist scholars like Comte believed only scientific methods rather than previous spiritual explanations for human behavior could advance.

Quantitative methods are an integral part of the five angles of analysis fostered by the data percolation methodology, which also includes qualitative methods, reviews of the literature including scholarly, interviews with experts and data processor simulation, and which forms an credit of data triangulation.

Quantitative methods have limitations. These studies do not render reasoning gradual participants' responses, they often do non reach underrepresented populations, and they may span long periods in lines tothe data.
