✍️ Short Note on Research Design

Research Design is the blueprint of research that guides the entire process of collecting, analyzing, and interpreting data. It provides a framework or plan that specifies the methods and procedures for conducting research. A good design ensures that the evidence obtained enables researchers to effectively address the research problem.

Functions of Research Design

• Ensures accuracy and reliability of results.
• Provides direction and removes bias.
• Helps in time and cost efficiency.
• Distinguishes between exploratory, descriptive, and causal research.

Phases of Research Design

1. Identifying the research problem.
2. Stating the objectives and hypothesis.
3. Selecting the research method (qualitative/quantitative).
4. Choosing sampling design.
5. Data collection methods.
6. Data analysis plan.
7. Reporting and conclusion.
