About Design and ResearchA Research design is the set of methods and procedure used in collecting and analyzing measures of the variables specified in the research problem. The design of study defines the study type (descriptive,correlation,semi-experiment,review,meta-analytic) and sub-type(descriptive-longitudinal case study,research problem,Hypothesis|hypothesis independent and dependent variables, Design of experiment|experimental design, and if application, data collection methods and a statistical analysis plan. Research design is the framework that has been created to find the answer to research questions.
Design types and Sub-typesThere are many ways to classify research designs but sometimes the distinction is artificial and other times different design are combined.
Nonetheless,the list below offers a number o useful distinctions between possible research designs. A research design is an arrangement of conditions of collections.
- Descriptive
- cor-relational
- Semi-experiment
- Experimental
- Review
- Meta-analytic
In some cases, these types coincide with quantitative and qualitative research and designs respectively. through this need not to be the case. In fixed designs, the design of the study is fixed before the main storage of data collection take place. Fixed designs are normally theory-driven; otherwise , it is impossible to know in advance which variables need to be controlled and measured. Often, these variables are measured quantitatively. Flexible designs allow for more freedom during the data collection process. One reason for using flexible research design can be that variable of interest is not quantitatively measurable, such as culture. In other cases, theory might not be available before one starts the research.
