Qualitative, quantitative and mixed methods dissertations What are they and which one should I choose? In the sections that follow, we briefly describe the main characteristics of qualitative, quantitative and mixed methods dissertations. Rather than being exhaustive, the main goal is to highlight what these types of research are and what they involve.
June 25, Doctoral research is the cornerstone of a PhD program. In order to write the dissertation, you must complete extensive, detailed research, and there are different types of research for different types of studies—involving very different methodology.
There are two primary dissertation research methods: Qualitative Qualitative research focuses on examining the topic via cultural phenomena, human behavior, or belief systems. The three most routinely used include: The research involves the use of multiple sources of data.
This might include interviews, field notes, documents, journals, and possibly some quantitative elements more information on quantitative research follows. A case study focuses on a particular problem or situation faced by a population and studies it from specific angles.
For example, a researcher might look at violence in the workplace, focusing on when, where, or how it occurs.
For example, take Hurricane Katrina. A researcher using this method will be trained during coursework and residencies in how to conduct this type of research, which involves specialized interviews and surveys with the people involved in the phenomenon.
Also called generic qualitative, generic inquiry, or other variations. So the researcher may be using similar methods, but will not have as thorough of a foundation of research available.
The researcher could run into problems with fewer data to analyze. Quantitative Quantitative research involves the empirical investigation of observable and measurable variables. It is used for theory testing, prediction of outcomes, and determining relationships between and among variables using statistical analysis.
In this approach, data are collected by the researcher. Participants are recruited for the study, informed consent is obtained, and quantitative data are obtained either electronically or in person by the researcher.
This approach allows the researcher to decide exactly what variables he or she is interested in exploring and how they will be operationalized in the study. Variables are measured using instruments whose psychometric properties reliability and validity have been established by other authors.
Data are analyzed using statistical techniques to assess the nature of the relationships between and among variables. This approach involves the statistical analysis of data collected by other researchers or organizations.
There are a number of publicly available data sets for researchers, often from large-scale, federally funded research projects or data repositories.
Secondary data analysis may save time for researchers as participant recruitment and data collection are avoided. It is also a way to access information about vulnerable populations in an ethical manner as it does not involve direct contact. However, when utilizing this approach, researchers must build their research questions based on the available data.
The choice of whether to use a qualitative or quantitative methodology is based on the nature of the questions being asked, the state of the field, and the feasibility of the approach with the population of interest.
