Research Design
Principles and methodologies for designing effective economic research
Research Design Principles
Design of Experiments (DoE) is a statistical methodology used to plan, conduct, analyze, and interpret experiments systematically. It helps identify significant factors affecting outcomes and determine optimal settings to achieve desired results.
Key Steps in Research Design:
- Identify the research problem or question
- Formulate hypotheses (null and alternative)
- Determine appropriate study design
- Construct research instruments
- Define sampling procedures
- Select variables and factors
- Design experimental plan
- Conduct pretesting
- Execute the research plan
- Analyze results and draw conclusions
Research Paradigms
Various philosophical perspectives have influenced the development of research methods throughout history. Understanding these perspectives helps researchers choose appropriate methodologies.
Classical Rationalism
Emphasizes reason in acquiring knowledge; reason precedes experience
Inductive Empiricism
Emphasizes observations and experiences; findings derived inductively
Logical Positivism
Focuses on empirical verification; separates science from metaphysics
Critical Rationalism
Emphasizes falsification; findings derived deductively
Social Constructivism
Focuses on social interaction and culture in knowledge construction
