When we use the word quantitative to describe quantitative dissertations , we do not simply mean that the dissertation will draw on quantitative research methods or statistical analysis techniques.
Classic routes that you can follow include replication-based studies , theory-driven research and data-driven dissertations.

They are mainly underpinned by positivist or post-positivist research paradigms. They draw on one of four broad quantitative research designs i.

They use research methods that generate quantitative data e.
They draw heavily on statistical analysis techniques to examine the data collected, whether descriptive or inferential in nature. They assess the quality of their findings in terms of their reliability , internal and external validity , and construct validity. You will learn more about the characteristics of quantitative dissertations, as well as being able to choose between the three classic routes that are pursued in quantitative research: Qualitative dissertations , like qualitative research in general, are often associated with qualitative research methods such as unstructured interviews, focus groups and participant observation.
Whilst they do use a set of research methods that are not used in quantitative dissertations, qualitative research is much more than a choice between research methods. Qualitative research takes a particular approach towards the research process , the setting of research questions , the development and use of theory , the choice of research strategy , the way that findings are presented and discussed, and so forth.
Overall, qualitative dissertations will be very different in approach, depending on the particular route that you adopt e. Classic routes that you can follow include autoethnographies , case study research , ethnographies , grounded theory , narrative research and phenomenological research. Researching a doctoral dissertation is an ongoing learning process.

For example, a researcher might look at violence in the workplace, focusing on when, where, or how it occurs. Professional dissertation consulting will assist you in the research design phase of your research. Selection of the Variable: Variables are selected on the basis of the predetermined theory that is statistically tested. Statistical expertise is needed when selecting the variable.
Statistical expertise and help is needed when selecting the sample size. If the sample size is small, the statistical test will not give accurate results. If the sample size is too large, then it will be more time consuming as well as costly.
