Quantitative techniques & data interpretation
Usually a big sample of data is collected – this would require verification, validation and recording before the analysis can take place. 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.

It is also possible that assigning numbers to fairly abstract constructs such as personal opinions risks making them spuriously s of quantitative most common sources of quantitative data include:Surveys, whether conducted online, by phone or in person.
The best way to work out which ones are right for your research is to discuss it with academic colleagues and your page analysing qualitative data provides more information about some of the most common y, it is important to say that there is no right and wrong answer to which methods you mes you may wish to use one single method, whether quantitative or qualitative, and sometimes you may want to use several, whether all one type or a mixture. Describe any limitations or unavoidable bias in your study and, if necessary, note why these limitations did not inhibit effective interpretation of the your study by to summarizing the topic and provide a final comment and assessment of the y of findings – synthesize the answers to your research questions. Natural sciences and social sciences, quantitative research is the systematic empirical investigation of observable phenomena via statistical, mathematical or computational techniques.
In these cases, the es a method for empirically determining an appropriate of the more common classical quantitative techniques are . Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. 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.
The methods section should be presented in the past population and sampling -- where did the data come from; how robust is it; note where gaps exist or what was excluded. 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. Further information about how to effectively present data using charts and graphs can be found tical analysis -- how did you analyze the data?
If there are no numbers involved, then it’s not quantitative phenomena obviously lend themselves to quantitative analysis because they are already available as numbers. The value of the parameter using all of le data, not just the sample data, is called the ter or true value of the parameter. 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.
Tative research is perhaps the simpler to define and data produced are always numerical, and they are analysed using mathematical and statistical methods. An experimental design includes subjects measured before and after a particular treatment, the sample population may be very small and purposefully chosen, and it is intended to establish causality between introduction to a quantitative study is usually written in the present tense and from the third person point of view. Generally, quantitative methods are designed to provide summaries of data that support generalizations about the phenomenon under study.

Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i.

However, instead of providing an interval, esis test attempts to refute a specific claim about tion parameter based on the sample data. Using quantitative methods, it is possible to give precise and testable expression to qualitative ideas. Research in mathematical sciences such as physics is also 'quantitative' by definition, though this use of the term differs in context.

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.
