Step 1: Consider your aims and approach
Before you can start designing your research, you should already have a clear idea of the research question you want to investigate.
Step 2: Choose a type of research design
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.
Step 3: Identify your population and sampling method
Your research design should clearly define who or what your research will focus on, and how you’ll go about choosing your participants or subjects.
Step 4: Choose your data collection methods
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.
Step 5: Plan your data collection procedures
As well as deciding on your methods, you need to plan exactly how you’ll use these methods to collect data that’s consistent, accurate, and unbiased.
Step 6: Decide on your data analysis strategies
On its own, raw data can’t answer your research question. The last step of designing your research is planning how you’ll analyze the data.
Frequently asked questions about research design

Why is case study research design important?
The case study research design is also useful for testing whether a specific theory and model actually applies to phenomena in the real world.
How does longitudinal research work?
A longitudinal study follows the same sample over time and makes repeated observations. For example, with longitudinal surveys, the same group of people is interviewed at regular intervals, enabling researchers to track changes over time and to relate them to variables that might explain why the changes occur. Longitudinal research designs describe patterns of change and help establish the direction and magnitude of causal relationships. Measurements are taken on each variable over two or more distinct time periods. This allows the researcher to measure change in variables over time. It is a type of observational study sometimes referred to as a panel study.
What is action research?
When practitioners use action research, it has the potential to increase the amount they learn consciously from their experience; the action research cycle can be regarded as a learning cycle. Action research studies often have direct and obvious relevance to improving practice and advocating for change.
What is social science research?
Social scientists, in particular, make wide use of this research design to examine contemporary real-life situations and provide the basis for the application of concepts and theories and the extension of methodologies. The design can provide detailed descriptions of specific and rare cases.
What is the causal effect?
Causal effect (nomothetic perspective) occurs when variation in one phenomenon, an independent variable, leads to or results, on average, in variation in another phenomenon, the dependent variable.
What is cohort study?
Often used in the medical sciences, but also found in the applied social sciences, a cohort study generally refers to a study conducted over a period of time involving members of a population which the subject or representative member comes from, and who are united by some commonality or similarity.
What are the different types of research design?
There are numerous ways to classify research design. Based on the purpose and method, we could distinguish among 5 research design types: 1. Descriptive research design. This is a theory-based design, where the researcher is primarily interested in describing the topic that is the subject of the research.
What is the research design?
At the beginning of every meaningful research, a researcher chooses a framework of methods and techniques to be used and applied in the research process. This framework is usually referred to as the research design.
Why is research design important?
Research design also supports the specific type of research (experiment, survey, review, case study, correlation, and so on) that needs to be done.
What is a theory based design?
This is a theory-based design, where the researcher is primarily interested in describing the topic that is the subject of the research. It is applied to case studies, naturalistic observations, surveys, and so on.
What is correlational design?
Just as its name suggests, correlational design allows the researcher to establish some kind of a relation between two closely related topics or variables. It’s a non-experimental research design type that requires at least two groups of data.
What is a quasi-experiment?
Whether it is a field experiment, a controlled experiment, or a quasi-experiment, this is one of the research design types that establishes a relation between the cause and effect of a particular happening.
What is diagnostic research?

What is research design?
The essence of research design is to translate a research problem into data for analysis so as to provide relevant answers to research questions at a minimum cost . This paper investigates what research design is, the different kinds of research design and how a researcher can choose the appropriate research design for his/her study. The study reveals that research design choice is guided by a careful analysis of statement of the problem, research questions, conceptual /theoretical framework and analyzing the relevant literature.
Why is computer literacy important?
Computer literacy is essential for a workforce to compete favorably in this increasingly computerized environment . Most organizations and institutions require a workforce that is computer literate. This calls for schools to equip more students with computer skills. Schools should be adequately equipped to offer hands-on experience and nurture rapid learning, yet be intuitive and interesting to students. Setting up and maintaining a computer laboratory goes with a cost which most schools cannot keep pace with thus the need to embrace other effective computer architectures. The aim of this research was to investigate the effectiveness of thin-client computing over stand-alone computing for service delivery in computer laboratories. Survey research method based on quantitative research design was adopted for this research. Data collection was done using a questionnaire, interview and observation. A sample size of thirty percent of the secondary schools which offer computer studies in Bungoma County was used for data collection. Stratified and simple random sampling techniques were used to select the schools to take part in the research. The research findings revealed that the main computer architectural configuration deployed by secondary schools for computer studies is stand-alone computer architecture. Thin-client computer architecture is more cost-effective compared to stand-alone computer architecture which if deployed in computer laboratories, schools will be able to offer computer studies to more students thus making more people computer literate.
