A well-planned research design helps ensure that your methods match your research aims dissertation methodology research design that you use the right kind of analysis for your data. You might have to write up a research design as a standalone assignment, or it might be part of a larger research proposal or other project.

In either case, you should carefully consider which methods are most appropriate and feasible for dissertation methodology research design your question. Table of contents Consider your aims and approach Choose a type of research design Identify your population and sampling method Choose your data collection methods Plan your data collection procedures Decide on your data analysis strategies Frequently asked questions about research design.

Before you can start designing your research, you dissertation methodology research design already have a clear idea of the research question you want to investigate. There are many different ways you could go about answering this question. Your research design choices should be driven by your aims and priorities—start by thinking carefully about what you dissertation methodology research design to achieve.

Qualitative research designs tend to be more flexible and inductiveallowing you to adjust your approach based on what you find throughout the research process. Quantitative research designs tend to be more fixed and deductivedissertation methodology research design, with variables and hypotheses clearly defined in advance of data collection. As well as scientific considerations, you also need to think practically when designing your research. At each stage of dissertation methodology research design research design process, make sure that your choices are practically feasible.

Within both qualitative and quantitative approaches, there are several types of research design to choose from.

Each type provides a framework for the overall shape of your research. Quantitative designs can be split into four main types, dissertation methodology research design. Experimental and quasi-experimental designs allow you to test cause-and-effect relationships, while descriptive and correlational designs allow you to measure variables and describe relationships between them.

With descriptive and correlational designs, you can get a clear picture of characteristics, trends and relationships as they exist in the real world. Any change in test scores could have been influenced by many other variables, such as increased stress and health issues among students and teachers. Experiments are the strongest way to test cause-and-effect relationships without the risk of other variables influencing the results.

However, their controlled conditions may not always reflect how things work in the real world. By comparing their outcomes in test scores, dissertation methodology research design, you can be more confident that it was the method of teaching and not other variables that caused any change in scores.

Types of qualitative research designs Qualitative designs are less strictly defined. This approach is about gaining a rich, detailed understanding of a specific context or phenomenon, and you can often be dissertation methodology research design creative and flexible in designing your research. The table below shows some common types of qualitative design.

They often have similar approaches in terms of data collection, but focus on different aspects when analyzing the data. Scribbr Plagiarism Checker. A population can be made up of anything you want to study—plants, dissertation methodology research design, animals, organizations, texts, countries, etc.

In the social sciences, it most often refers to a group of people. For example, will you focus on people from a specific demographic, region or background?

Are you interested in people with a certain job or medical condition, or users of a particular product? The more precisely you define your population, the easier it will be to gather a representative sample, dissertation methodology research design.

To make the research more dissertation methodology research design, and to draw more precise conclusions, you could focus on a narrower population—for example, 9th-grade students in low-income areas of New York. To select a sample, there are two main approaches: probability sampling and non-probability sampling. The sampling method you use affects how confidently you can generalize your results to the population as a whole.

For example, in an ethnography or a case study, your aim is to deeply understand a specific context, not to generalize to a population. Instead of sampling, you may simply aim to collect as much data as possible about the context you are studying.

In these types of design, you still have to carefully consider your choice of case or community. You should have a clear rationale for why this particular case is suitable for answering your research question. For example, you might choose a case study that reveals an unusual or neglected aspect of your research problem, or you might choose several very similar or very different cases in order to compare them.

Data collection methods are ways of directly measuring variables and gathering information. They allow you to gain first-hand knowledge and original insights into your research problem, dissertation methodology research design. Surveys allow you to collect data about opinions, behaviours, experiences, and characteristics by asking people directly. There are two main survey methods dissertation methodology research design choose from: questionnaires and interviews.

Observations allow you to collect data unobtrusively, observing characteristics, dissertation methodology research design, behaviours or social interactions without relying on self-reporting. Observations may be conducted in real time, taking notes as you observe, or you might make audiovisual recordings for later analysis. They can be qualitative or quantitative. Using secondary data can expand the scope of your research, as you may be able to access much larger and more varied samples than you could collect yourself.

Planning systematic procedures is especially important in quantitative research, where you need to precisely define your variables and ensure your measurements are reliable and valid. Some variables, like height or age, are easily measured. Operationalization means turning these fuzzy ideas into measurable indicators. For valid and reliable results, your measurement materials should be thoroughly researched and carefully designed.

Plan your procedures to make sure you carry out the same steps in the same way for each participant. How will you ensure a high response rate? Will you need to transcribe interviews or perform data entry for observations? Keeping your data well-organized will save time when it comes to analyzing it. It can also help other researchers validate and add to your findings. With statistics, you can summarize your sample data, make estimates, and test hypotheses.

Using descriptive statisticsyou can summarize your sample data in terms of:. The specific calculations you can do depend on the level of measurement of your variables. Using inferential statisticsyou can:. Regression and correlation tests look for associations between two or more variables, while comparison tests such as t-tests and ANOVAs look for differences in the outcomes of different groups.

In qualitative research, your data will usually be very dense with information and ideas. Two of the most common approaches to doing this are thematic analysis and discourse analysis, dissertation methodology research design. There are many other ways of analyzing qualitative data depending on the aims of your research.

To get a sense of potential approaches, try reading some qualitative research papers in your field. A research design is a strategy for answering your research question.

It defines your overall approach and determines how you will collect and analyze data. A well-planned research design helps ensure that your methods match your research aims, that you collect high-quality data, and that you use the right kind of analysis to answer your questions, utilizing credible sources. This allows you to dissertation methodology research design validtrustworthy conclusions. Quantitative research designs can be divided into two main categories:.
