The Different Ways to Collect and Analyze Data: Methods Used in Research
Researchers develop a dissertation methodology as a framework for all components of the dissertation research process. The dissertation methodology includes potential data sources, methods for screening or recruiting participants, how to ask questions, using technology devices if necessary, and ethical considerations. Knowing what type of study you will be doing before collecting and analyzing data should reduce the time and effort involved in your dissertation project.
Data can be collected and analyzed in three ways: qualitative, quantitative, and mixed methods (see below for definitions). Researchers typically choose one method to use throughout their dissertation; however, some dissertation studies incorporate more than one type of research design.
Qualitative dissertation study designs include developing a plan for collecting and analyzing data to provide a complete description of a phenomenon within its real-life context. Data is collected from individuals who have had the same experience with the chosen topic, such as parents with children in college, victims of crime, or physicians providing care for patients living with chronic pain. It is data-rich, which means it can be analyzed in many different ways to provide multiple perspectives. Depending on the type of dissertation study, this dissertation methodology often includes interviews with participants or observations of them completing specific tasks.
Quantitative dissertation study designs are used to identify relationships between variables. This dissertation methodology typically uses large samples of people who are not experiencing the studied phenomena. For example, researchers might collect survey data from hundreds of students at one university to identify factors related to students' academic performance. This dissertation methodology includes collecting data through surveys, experiments, or both.
Mixed methods dissertation study designs combine both qualitative and quantitative dissertation study techniques to gain a complete understanding of phenomena. For example, researchers might want to understand an individual's experience using a new technology device that the dissertation study participant just acquired. In this dissertation methodology, qualitative data is collected through interviews, and quantitative information is collected by having participants keep a diary for one week about their experiences with the technology device.
After reviewing dissertation study designs, researchers should decide which type of dissertation methodology is most appropriate for their studies. For example, suppose the dissertation study will be exploring relationships between variables in quantitative dissertation study designs. In that case, the dissertation research question may be better suited to this methodology than the qualitative dissertation study design. When developing a dissertation methodology, it is essential to consider dissertation participants and be involved in the dissertation research. Researchers should keep dissertation study participants' safety and human rights as a priority and choose dissertation methodology that minimizes any potential harm to them or negative consequences of participating.
A dissertation methodology helps you create a plan for how your dissertation project will be conducted from beginning to end. It is used as a guide during dissertation research, which is different from dissertation study designs. It is important to remember that dissertation study design and dissertation methodology are not the same things! Not understanding this difference may lead to poor dissertation results, so it is vital to know how to collect and analyze data before beginning your dissertation project.
As you begin developing dissertation study designs, there are a few dissertation study design types that can be considered as dissertation methodology options:
Qualitative dissertation study designs include developing a plan for collecting and analyzing data to provide a complete description of a phenomenon within its real-life context. Data is collected from individuals who have had the same experience with the chosen topic, such as parents with children in college, victims of crime, or physicians providing care for patients living with chronic pain. It is data-rich, which means it can be analyzed in many different ways to provide multiple perspectives. There are a few dissertation study design types within the qualitative dissertation methodology:
Qualitative dissertation methodology includes collecting data through interviews with dissertation study participants or observations of dissertation study participants. For example, a dissertation researcher wanting to understand parents' experiences with children attending college may interview dissertation participants about their experiences or have dissertation participants keep a diary for six months about specific issues that relate to being a parent in college.
A dissertation methodology that includes both qualitative and quantitative dissertation study designs is considered using a mixed methods dissertation methodology. For example, dissertation researchers may ask dissertation study participants to complete questionnaires or surveys about their experiences with a service organization. A dissertation researcher may also conduct in-depth interviews with dissertation study participants involved with the service organization to understand what they found most helpful when utilizing the services provided by the organization.
