Conceptual framework

Conceptual frameworks (also called theoretical frameworks) are a type of intermediate theory that have the potential to connect to all aspects of inquiry (e.g., problem definition, purpose, literature review, methodology, data collection and analysis). Conceptual frameworks act like maps that give coherence to empirical inquiry. Because conceptual frameworks are potentially so close to empirical inquiry, they take different forms depending upon the research question or problem. Shields and Tajalli (2006) have identified several types of conceptual frameworks (working hypotheses, descriptive categories, practical ideal type, models of operations research and formal hypotheses) for the field of public administration. The frameworks are linked to particular research purposes (exploration, description, gauging, decision making and explanation/prediction). When purpose and framework are aligned other aspects of empirical research such as choice of methodology (survey, interviews, analysis of existing data, direct observation, focus groups etc) and type of statistical technique become obvious.
