Any scientific paper needs to be verifiable by other researchers, so that they can review the results by replicating the experiment themselves and testing the validity.
To encourage this, you need to give a completely accurate description of the equipment and the techniques used for gathering the data.
The focus should be on how you applied a method, not on the mechanics of doing a method.
An exception to this rule is if you select an unconventional approach to doing the method; if this is the case, be sure to explain why this approach was chosen and how it enhances the overall research process.
Laying out your methodology allows the reader to make their own decision about the validity of the data and understand how this may have produced the results it did.
If the research about shopping preferences were built on a single case study, it would have little external validity.For example, in a psychology paper, there is no need to describe a Skinner box, as it’s design is well known to psychologists.However, you would need to explain exactly how the box was used, to allow exact replication.It is almost a given that you will encounter problems when collecting or generating your data.Do not ignore these problems or pretend they did not occur. Don't avoid using a quantitative approach to analyzing your research problem just because you fear the idea of applying statistical designs and tests.The reader would rightly see these results very differently from those of a study with a more vigorous experimental design and thousands of participants.This is the very basic structure behind your methodology, and lays out the most important aspects of how you actually carried out your research.Finally, you must provide an explanation of how the raw data was compiled and analyzed.In science, you are (hopefully) never presenting a personal opinion or arguing for preconceived biases.Often, documenting how you overcame obstacles can form an interesting part of the methodology. The Structure, Format, Content, and Style of a Journal-Style Scientific Paper. A qualitative approach, such as conducting interviews or content analysis of archival texts, can yield exciting new insights about a research problem, but it should not be undertaken simply because you have a disdain for running a simple regression.It demonstrates to the reader that you can provide a cogent rationale for the decisions you made to minimize the impact of any problems that arose.

A well designed quantitative research study can often be accomplished in very clear and direct ways, whereas, a similar study of a qualitative nature usually requires considerable time to analyze large volumes of data and a tremendous burden to create new paths for analysis where previously no path associated with your research problem had existed.
