A research design is the set of methods and procedures used in collecting and analyzing measures of the variables specified in a problem theory. The research design defines the study type (e.g. review, descriptive, correlational, experimental or meta-analytic) and sub-type (e.g. longitudinal, cross-section, cohort, . . .), research problem, hypotheses, independent and dependent variables, experimental design, and, if applicable, data collection methods (survey, systems, ….) and a statistical analysis plan. A research design is a framework that has been created to find answers to research questions.
