Qualitative Research

While defining quantitative and qualitative research based on their uses and purposes may be considered a practical approach for researcher, the difference actually lies on their roots: Procedures, designs, concepts, purposes and uses emanate from there. Example on qualitative research referring to quality where problems are answered without generally focusing on quantity, are descriptions in words coming form interviews, discussions or observations.

However when words are translated to quantity in order to describe or to generalize, then the research is now called quantitatitive research. The bottom lines are the questions: Many thanks for giving me clear understanding around the differences between the qualitative and quantative research. Thanks a millions time. I was struggling to get an idea of how to approach the definitions. In fact I was even hesitating to answer the questions confidently.

Thanks for the distinct comparison between qualitative and quantitative Research, very very helpful. Thank you for making me to understand the difference between qualitative Research and quantitative research. Thanks a lot for the insightful distinction between Qualitative and Quantitative research. However, the differences as you enumerated did not factor in the advantages and disadvantages of both research tools.

My special thanks goes to Camilo Tabinas for suggesting that the difference between quantitative and qualitative research method stems from the roots of quantity and quality. Quantitative approach stems from the ontological view that objective reality exist independently of human perception Slevitch, Qualitative and quantitative methodologies compared: In classical physics, the theory and definitions which underpin measurement are generally deterministic in nature.

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 sciences. Quantitative research may involve the use of proxies as stand-ins for other quantities that cannot be directly measured.

Tree-ring width, for example, is considered a reliable proxy of ambient environmental conditions such as the warmth of growing seasons or amount of rainfall. 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 A.

When used in this way, the proxy record tree ring width, say only reconstructs a certain amount of the variance of the original record. The proxy may be calibrated for example, during the period of the instrumental record to determine how much variation is captured, including whether both short and long term variation is revealed. In the case of tree-ring width, different species in different places may show more or less sensitivity to, say, rainfall or temperature: In most physical and biological sciences , the use of either quantitative or qualitative methods is uncontroversial, and each is used when appropriate.

In the social sciences, particularly in sociology , social anthropology and psychology , the use of one or other type of method can be a matter of controversy and even ideology, with particular schools of thought within each discipline favouring one type of method and pouring scorn on to the other. The majority tendency throughout the history of social science, however, is to use eclectic approaches-by combining both methods.

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. From Wikipedia, the free encyclopedia. This article has multiple issues.

A sound quantitative design should only manipulate one variable at a time, or statistical analysis becomes cumbersome and open to question. Ideally, the research should be constructed in a manner that allows others to repeat the experiment and obtain similar results.

When to perform the quantitative research design. 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. After statistical analysis of the results, a comprehensive answer is reached, and the results can be legitimately discussed and published.

Quantitative experiments also filter out external factors, if properly designed, and so the results gained can be seen as real and unbiased. Quantitative experiments are useful for testing the results gained by a series of qualitative experiments, leading to a final answer, and a narrowing down of possible directions for follow up research to take. Quantitative experiments can be difficult and expensive and require a lot of time to perform.

They must be carefully planned to ensure that there is complete randomization and correct designation of control groups. Quantitative studies usually require extensive statistical analysis, which can be difficult, due to most scientists not being statisticians. The field of statistical study is a whole scientific discipline and can be difficult for non-mathematicians.

Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality. Quantitative research deals in numbers, logic, and an objective stance.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.

What is quantitative research? Research methods in education (and the other social sciences) are often methods. The last part of the definition refers to the use of mathematically based methods, in particular statistics, to analyse the data. would seem that quantitative and qualitative research methods are pretty incompatible. These. research, when to use and not to use quantitative methods, advantages, common approaches and samples of quantitative research, and common misconceptions. Besides, a set of criteria for the definition. In quantitative research we collect numerical data. This is closely connected to the final part of the definition: analysis using.
