Question

1. list the three types of research and discuss them with their advantages and disadvantages
2. state the difference between designs and methodology.

Answer 1

1) Three types of research
- Quantitative research
- What it is: Studies phenomena using numerical measurement and statistical analysis to test hypotheses or estimate relationships. Often deductive and positivist.
- Common methods: surveys with closed questions, experiments, structured observations, secondary data/statistical analysis.
- Advantages:
- Can measure magnitude and frequency; permits statistical inference and generalization (if sampling is appropriate).
- Results often considered objective and replicable.
- Good for testing theory and estimating effects/relationships.
- Disadvantages:
- May miss context, meaning, or complexity behind numbers.
- Instruments can force artificial categories; responses may lack depth.
- Rigid design can be less adaptable to emergent findings.

- Qualitative research
- What it is: Explores meanings, experiences, and processes in depth, using non‑numeric data (text, images, audio). Often inductive and interpretivist/constructivist.
- Common methods: interviews, focus groups, participant observation, document analysis, case studies.
- Advantages:
- Produces rich, contextualized understanding of why and how things happen.
- Flexible and able to capture unexpected phenomena and nuance.
- Useful for theory generation and exploring new or complex issues.
- Disadvantages:
- Findings are often not statistically generalizable.
- Analysis can be time‑consuming and influenced by researcher interpretation (subjectivity).
- Harder to demonstrate reliability and to replicate exactly.

- Mixed methods research
- What it is: Integrates quantitative and qualitative approaches in a single study (or series of linked studies) to capitalize on strengths of both.
- Common designs: concurrent triangulation (collect both types simultaneously), explanatory sequential (quant → qual), exploratory sequential (qual → quant).
- Advantages:
- Provides both breadth (numbers) and depth (context), enabling more complete answers.
- Can corroborate findings across methods (triangulation) and produce more pragmatic, actionable results.
- Disadvantages:
- More complex to design, implement, and interpret; requires skill in both paradigms.
- Takes more time and resources; potential for conflicting results that are hard to reconcile.
- Reporting must balance both strands clearly, which can be challenging.

2) Difference between research design and methodology
- Methodology:
- Definition: The overarching rationale and philosophical framework guiding the research — why you choose particular approaches and how they fit the research questions. It includes the research paradigm (e.g., positivist, interpretivist), the general strategy (quantitative, qualitative, mixed), and justification for chosen methods.
- Scope: Broad; explains the logic behind the study and the appropriateness of approaches for answering the research question.

- Research design:
- Definition: The specific blueprint or plan for conducting the study — how you will collect and analyze data to answer the question. It specifies sampling, procedures, instruments, timing (cross‑sectional vs longitudinal), controls, and analytic techniques.
- Scope: Concrete and practical; operationalizes the methodology.

- Short comparison (practical)
- Methodology = why and what approach (philosophy + strategy).
- Design = how (the operational plan and steps).
- Example: If your methodology is qualitative (constructivist) to explore lived experience, your design might be a phenomenological study using purposive sampling, semi‑structured interviews, and thematic analysis. Methods are the actual tools and procedures (interview guide, recording, coding scheme) used inside that design.

If you want, I can give sample study outlines showing methodology → design → methods for a quantitative, qualitative, and mixed study.
