Research Formulation and Design
Detailed explanation — point by point
Foundation of any scientific or academic investigation · determines what, why, and how
1. Motivation and Objectives of Research
Motivation of Research
Main motivations:
- Desire to obtain a research degree – e.g. PhD, M.Phil., Master's dissertation.
- Desire to solve unsolved problems – e.g. renewable energy solutions.
- Intellectual curiosity – to discover new knowledge.
- Desire to serve society – e.g. research on disease prevention.
- Career advancement – publication and professional growth.
- Recognition and prestige – building academic reputation.
- Government or industrial requirements – sponsored research projects.
Objectives of Research
Major objectives: gain familiarity with a phenomenon; verify existing theories; discover relationships among variables; generate new knowledge; solve practical problems; predict future outcomes.
Example: Research Topic: "Impact of social media on student performance"
Objectives: Analyze student social media usage · Study effect on academic achievement · Suggest improvement measures.
2. Research Methods vs Methodology
| Research Methods | Research Methodology |
| Techniques used to collect data | Science of studying methods |
| Practical implementation | Theoretical framework |
| Focuses on “How” | Focuses on “Why” |
| Example: Survey, interview | Example: Justification for choosing survey |
Example: If studying customer satisfaction: Method: Questionnaire · Methodology: Explains why questionnaire is suitable.
3. Types of Research
A. Descriptive vs Analytical Research
| Descriptive Research | Analytical Research |
Describes characteristics of existing situations. Purpose: Answer What, Where, When Methods: Survey, observation, case studies. Example: Surveying customer satisfaction. Features: No variable manipulation, fact collection. |
Uses existing information to evaluate and analyze. Purpose: Answer Why and How Example: Studying reasons for customer dissatisfaction. Features: Critical thinking, interpretation of data. |
B. Applied vs Fundamental Research
| Applied Research | Fundamental (Basic) Research |
Conducted to solve real-world problems. Goal: Immediate practical application. Example: Developing improved crop fertilizers. Characteristics: Problem-oriented, industry-oriented. |
Conducted to increase knowledge. Goal: Theory development. Example: Studying molecular structure. Characteristics: Long-term benefits, expands understanding. |
Concept of Applied and Basic Research Process
- Applied Research Process: Problem → Data Collection → Analysis → Practical Solution. Example: Traffic congestion → Data → Analysis → New traffic model.
- Basic Research Process: Observation → Theory → Experiment → Knowledge. Example: Study atoms → Develop theory.
C. Quantitative vs Qualitative Research
| Quantitative Research | Qualitative Research |
Deals with numerical data. Methods: Statistical analysis, surveys. Example: Measuring exam scores. Characteristics: Objective, large sample. |
Deals with opinions and experiences. Methods: Interviews, observation. Example: Understanding student emotions. Characteristics: Subjective, small sample. |
D. Conceptual vs Empirical Research
| Conceptual Research | Empirical Research |
Based on ideas and theories. Example: Developing economic theories. Characteristics: No experiments, abstract thinking. |
Based on observation and experiments. Example: Testing a drug clinically. Characteristics: Data-driven, evidence-based. |
4. Criteria of Good Research
- Clearly Defined Purpose – objective precise.
- Systematic Process – steps follow sequence.
- Valid Data Collection – reliable instruments.
- Accuracy – results correct.
- Objectivity – avoid personal bias.
- Replicability – others obtain similar results.
- Ethical Standards – no plagiarism or manipulation.
- Logical Conclusions – derived from evidence.
5. Defining and Formulating the Research Problem
Research Problem – a specific issue selected for investigation.
Example: Poor academic performance among students.
Steps in Problem Formulation
- Identify broad area – e.g. Education
- Narrow topic – e.g. Student performance
- Define variables – Independent: social media use; Dependent: academic performance
- Form research questions
- Develop objectives
6. Selecting the Research Problem
Factors to consider:
- Interest – researcher should be interested.
- Feasibility – time and resources available.
- Availability of Data – data accessible.
- Social Relevance – useful to society.
- Originality – avoid duplication.
7. Necessity of Defining the Problem
- Gives research direction
- Saves time and cost
- Avoids unnecessary data
- Improves accuracy
- Helps formulate hypothesis
Example: Poor problem definition → Wrong conclusions.
8. Importance of Literature Review in Defining a Problem
Literature Review – systematic study of previous work.
- Understand existing knowledge
- Avoid duplication
- Discover research gaps
- Improve methodology
- Refine objectives
9. Literature Review – Sources
Primary Sources
- Research articles
- Conference papers
- Patents
- Experimental reports
- Thesis
Advantages: Authentic, detailed.
Secondary Sources
- Review papers
- Books
- Encyclopedias
Advantages: Easier understanding.
10. Reviews, Monograph, Patents
- Review Article – summarizes existing studies (e.g. review of cancer treatments). Types: narrative review, systematic review, meta-analysis.
- Monograph – detailed publication on a single subject (e.g. entire book on nanotechnology). Characteristics: in-depth analysis, scholarly work.
- Patent – legal protection for inventions. Purpose: protect innovation, prevent copying. Components: Title, Abstract, Claims, Drawings.
11. Research Databases
Examples: Google Scholar, PubMed, Scopus, Web of Science, IEEE Xplore, ScienceDirect, SpringerLink.
12. Web as a Source of Literature
Advantages: fast access, global information. Limitations: reliability concerns, information overload.
13. Searching the Web for Research
- Use Keywords – e.g. “machine learning healthcare applications”
- Boolean Operators – AND, OR, NOT (e.g. Education AND Technology)
- Exact Phrase Search – use quotes: "Artificial Intelligence"
- Use Filters – year, author, publication type
14. Critical Literature Review
Critical review means evaluating literature, not only summarizing.
Steps:
- Read thoroughly
- Compare studies
- Identify strengths
- Identify limitations
- Analyze methodology
- Draw conclusions
Questions: What was studied? How was it studied? What were limitations?
15. Identifying Gap Areas from Literature and Research Database
Research Gap – area that previous research has not fully addressed.
Types: knowledge gap, methodological gap, population gap, theoretical gap.
Process: Collect studies → Compare findings → Identify limitations → Find unanswered questions.
Example: Previous studies: social media effects on college students. Gap: No study on rural school students.
16. Development of Working Hypothesis
Hypothesis – tentative assumption to be tested.
“Higher social media use reduces academic performance.”
Characteristics of Good Hypothesis
- Clear
- Specific
- Testable
- Logical
- Measurable
Steps to Develop Hypothesis
- Define problem
- Review literature
- Identify variables
- Build assumptions
- Form testable statement
Types of Hypothesis
- Null Hypothesis (H₀) – no relationship exists. Example: Social media has no effect.
- Alternative Hypothesis (H₁) – relationship exists. Example: Social media affects performance.
