🔥 Most Repeated Question: Qualities and Criteria of Good Research
Answer — Section A (~450 words):
Meaning and Importance: Research is a systematic, controlled, empirical, and critical examination of hypothetical propositions about presumed relations among natural phenomena. Good research is distinguished from poor research not merely by its findings but by the rigour, transparency, and ethics of its process.
Criteria/Qualities of Good Research:
1. Purposiveness Good research is directed toward a clear, well-defined problem. The researcher must state the objectives precisely so that the study remains focused and findings are interpretable. Vague or overly broad research questions undermine purposiveness.
2. Rigor Research must be conducted with appropriate care and thoroughness. This encompasses: (a) use of proper sampling, (b) precise operationalisation of variables, (c) selection of appropriate research design, and (d) use of valid and reliable measurement tools.
3. Testability Hypotheses must be empirically testable — capable of being confirmed or refuted by data. Non-falsifiable claims lie outside the domain of scientific research. Testability ensures that research is open to critical scrutiny.
4. Replicability Good research should be replicable by other researchers using the same methods. Replicability requires sufficient methodological transparency — detailed description of participants, instruments, procedures, and analysis.
5. Precision and Confidence Findings should be reported with appropriate precision (close to true values) and with an indication of confidence (probability of error). Use of confidence intervals and effect sizes satisfies this criterion.
6. Objectivity Conclusions should be based on data rather than the researcher's personal beliefs or biases. Objectivity is approximated through standardised procedures, blind rating, peer review, and transparency about limitations.
7. Parsimony (Economy of Explanation) When two explanations account for the data equally well, the simpler one is preferred (Occam's Razor). Parsimonious theories are more generalisable and easier to test.
8. Generalisability (External Validity) Good research findings should apply beyond the immediate sample and setting. Generalisability depends on representativeness of sampling and ecological validity of the research context.
9. Ethical Integrity Research must conform to ethical standards: informed consent, confidentiality, right to withdraw, absence of deception (or full debriefing when used), and protection from harm.
Objectives of Research in Psychology: (a) Description — systematically describe phenomena (e.g., prevalence of depression). (b) Explanation/Understanding — identify causes and antecedents. (c) Prediction — forecast future behaviour from known variables. (d) Control/Application — use knowledge to modify behaviour or conditions for human benefit.
Significance of Research Methods:
- Enables psychology to move beyond intuition, common sense, and authority.
- Allows accumulation of verified knowledge.
- Forms the foundation for clinical, educational, and organisational interventions.
- Protects against biases that distort informal observation.
📝 Short Note Version (Section C — ~120 words)
Qualities of Good Research: Good research is characterised by: (1) Purposiveness — a clear, focused research question; (2) Rigor — careful design and measurement; (3) Testability — falsifiable hypotheses; (4) Replicability — methods transparent enough to repeat; (5) Objectivity — conclusions based on data, not bias; (6) Parsimony — simplest adequate explanation; (7) Generalisability — findings applicable beyond the sample; and (8) Ethical integrity — rights of participants protected. Kerlinger (1986) added that scientific research must be controlled, empirical, and critical. Together these criteria distinguish rigorous scientific research from anecdote, speculation, or advocacy.
