About Design and Research A 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-types There 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-ex...
