RESEARCH DESIGN
A research design is the set of methods and procedures used in collecting and analysing measures of the variables specified in the research problem. The design is the structure of any scientific work. It gives direction and systematizes the research. Different types of research designs have different advantages and disadvantages.
Design types and sub-types:
There are many ways to classify research designs, but sometimes the distinction is artificial and other times different designs are combined. Nonetheless, the list below offers a number of useful distinctions between possible research designs. A research design is an arrangement of conditions or collections.
- Descriptive (e.g., case-study, naturalistic observation, survey)
- Correlational (e.g., case-control study, observational study)
- Semi-experimental (e.g., field experiment, quasi-experiment)
- Experimental (experiment with random assignment)
- Review (literature review, systematic review)
- Meta-analytic (meta-analysis)
