  • UGC NET – UNIT–II: RESEARCH APTITUDE (RESEARCH METHODOLOGY)

    🌱 1. Meaning of Research

    Definition:

    “Research is a systematic and objective process of collecting, analyzing, and interpreting information to find answers to certain questions or problems.”
    — Clifford Woody

    Key Characteristics:

    • Systematic: Follows an ordered sequence of steps.

    • Empirical: Based on observation or experience.

    • Controlled: Variables are identified and managed.

    • Objective: Free from personal bias.

    • Replicable: Others can verify or repeat the results.

    Purpose of Research:

    1. To discover new facts or verify existing facts.

    2. To analyze relationships between variables.

    3. To test hypotheses and develop new theories.

    4. To apply findings to practical problems.

    🧩 2. Objectives of Research

    • Exploration: To gain familiarity with phenomena or problems.

    • Description: To describe characteristics or functions.

    • Explanation: To explain causal relationships.

    • Prediction: To forecast future occurrences.

    • Control/Action: To solve practical problems.

    🧠 3. Types of Research

    (A) Based on Purpose

    Type Description Example
    Basic (Pure) Adds new knowledge without immediate application. Einstein’s theory of relativity.
    Applied Solves specific, practical problems. Developing a new teaching method.
    Action Research Conducted by practitioners to improve their own practice. A teacher improving classroom participation.
    Evaluative Measures the effectiveness of a program or policy. Evaluating a literacy program.

    (B) Based on Method

    Type Key Feature Example
    Descriptive Describes characteristics of a population or situation. Survey of teaching attitudes.
    Analytical Uses already available facts to analyze relationships. Historical data analysis.
    Experimental Involves manipulation of variables. Testing a new learning app.
    Historical Studies past records and trends. History of education system.
    Qualitative Non-numerical, interpretative. Case studies, interviews.
    Quantitative Numerical, statistical. Correlation studies, regression.

    ⚙️ 4. Approaches to Research

    Approach Focus Example
    Positivism Objective reality, quantitative data, hypothesis testing. Statistical social research.
    Post-Positivism Accepts that reality can’t be fully known, uses both qualitative and quantitative data. Mixed-method research.
    Interpretivism Subjective meaning and understanding of human behavior. Ethnographic studies.
    Critical Theory Focus on social change, power, and justice. Feminist research, Marxist analysis.

    🧭 5. Steps in the Research Process

    1. Identification of Problem – Select a topic or issue worth studying.

    2. Review of Literature – Study past work and identify gaps.

    3. Formulation of Hypothesis/Research Questions – Define testable statements.

    4. Research Design – Blueprint of research (methods, tools, sampling).

    5. Data Collection – Primary or secondary data.

    6. Data Analysis and Interpretation – Apply statistical or logical techniques.

    7. Testing of Hypothesis – Accept or reject based on analysis.

    8. Reporting and Documentation – Writing thesis, report, or paper.

    📚 6. Hypothesis

    Definition:

    A hypothesis is a tentative statement about the relationship between two or more variables that can be tested empirically.

    Types:

    • Null Hypothesis (H₀): No relationship or difference exists.

    • Alternative Hypothesis (H₁): Predicts a specific relationship or difference.

    • Directional Hypothesis: Specifies the direction of the relationship.

    • Non-Directional Hypothesis: Indicates only that a relationship exists.

    Characteristics of a Good Hypothesis:

    • Clear and specific

    • Testable and measurable

    • Based on theory or prior research

    • Limited in scope

    • Consistent with existing knowledge

    🔍 7. Research Design

    Meaning:

    A research design is the plan, structure, and strategy of investigation conceived to obtain answers to research questions.

    Types:

    1. Exploratory Design: For preliminary understanding (e.g., interviews, case studies).

    2. Descriptive Design: To describe characteristics (e.g., surveys).

    3. Experimental Design: For testing cause-effect relationships.

    4. Correlational Design: For studying relationships between variables.

    📊 8. Sampling

    Definition:

    Sampling is the process of selecting a subset of individuals from a population to represent the entire group.

    Types:

    A. Probability Sampling (Equal chance of selection)

    • Simple Random Sampling

    • Stratified Sampling

    • Cluster Sampling

    • Systematic Sampling

    B. Non-Probability Sampling (Non-random)

    • Convenience Sampling

    • Purposive Sampling

    • Quota Sampling

    • Snowball Sampling

    📈 9. Data Collection Methods

    Type Techniques Examples
    Primary Data Questionnaire, Interviews, Observation, Experiments Field surveys
    Secondary Data Books, Journals, Government reports, Databases Census data

    💡 10. Qualitative vs Quantitative Research

    Basis Qualitative Quantitative
    Nature Subjective Objective
    Data Words, images Numbers
    Tools Interviews, focus groups Surveys, experiments
    Analysis Thematic, narrative Statistical
    Goal Understanding meaning Testing hypotheses

    🧾 11. Data Analysis and Interpretation

    • Quantitative: Statistical techniques — Mean, Median, Mode, Correlation, Regression, t-test, ANOVA, Chi-square.

    • Qualitative: Content analysis, thematic analysis, coding of textual data.

    Interpretation involves explaining patterns, drawing conclusions, and relating findings to theory.
