The key principles of research design brought together in material on measurement principles, sampling and case study, survey and experimentation is termed as -

Correct option is B

The term "Research Methods" refers to the collection of key principles and approaches utilized in the structure of research designs. This includes measurement principles, sampling, case study approaches, survey techniques, and experimentation. Research methods encompass various techniques and protocols aimed at effectively gathering, measuring, and analyzing data.
Information Booster:
1. Definition of Research Methods: Encompasses systematic approaches and processes by which data is gathered and analyzed for specific study objectives.
2. Components in Research: Includes techniques like sampling (for selecting subjects), survey methods (for data collection), and experimentation (to test hypotheses).
3. Research Design vs. Research Methods: While research design provides the framework, research methods are the techniques used within this framework to conduct the study.
4. Importance in Research Studies: Consistent and accurate application of methods ensures replicability and reliability of results, which is essential for the validity of research outcomes.
Additional Information:
· (a) Research Methodology: Refers to the theoretical and philosophical framework that guides the choice of research methods, discussing why certain methods are used over others. It encompasses the justification and rationale behind choosing specific research approaches.
· (c) Research Techniques: Involves specific tools and procedures (e.g., surveys, interviews) used within research methods but is narrower in scope and does not typically cover broader design or sampling principles.
· (d) Research Design: Refers to the overall structure or blueprint of the research, detailing the systematic plan for the study, rather than focusing on the specific techniques or processes used for data collection and analysis.
