| Chapter | Core Topic | Chapter Summary & Key Concepts | | :--- | :--- | :--- | | | Research Methodology: An Introduction | Defines research, its objectives, and the various types of research (descriptive, analytical, applied, fundamental, quantitative, qualitative). It establishes the research process flow. | | 2 | Defining the Research Problem | A crucial step that involves selecting a problem, understanding its nature, reviewing literature, and finally stating the problem clearly. It discusses criteria like feasibility and a researcher's expertise. | | 3 | Research Design | The conceptual blueprint of research that outlines the methods for data collection, measurement, and analysis. It details different types of designs like exploratory, descriptive, and experimental. | | 4 | Sampling Design | The selection of a subset (sample) from a larger population to estimate characteristics of the whole population. It covers probability and non-probability sampling methods. | | 5 | Measurement and Scaling Techniques | Introduction to different scales of measurement (nominal, ordinal, interval, ratio) and techniques for developing scales to measure abstract concepts. | | 6 | Methods of Data Collection | Explores primary data collection methods (observation, interviews, questionnaires, surveys) and secondary data sources, highlighting their merits and demerits. | | 7 | Processing and Analysis of Data | The steps after data collection: editing, coding, classification, and tabulation to prepare data for statistical analysis. | | 8 | Sampling Fundamentals | Delves deeper into the theory of sampling, exploring concepts like sampling distribution, standard error, and the logic behind making inferences about a population based on a sample. | | 9 | Testing of Hypotheses I (Parametric Tests) | Introduces parametric tests (t-test, z-test, F-test) used when data is assumed to follow a specific probability distribution. It explains the logic of hypothesis testing. | | 10 | Chi-Square Test | A detailed look at the non-parametric Chi-square test, which is used to analyze categorical data and test for independence between variables. | | 11 | Analysis of Variance and Co-variance | An explanation of ANOVA (Analysis of Variance) and ANCOVA (Analysis of Co-variance), which are used to test for differences among several group means. | | 12 | The Computer: Its Role in Research | A new chapter in the second edition that acknowledges the growing importance of computers for data management and advanced statistical analysis in social science research. | What is your

Kothari smiled. “In the physical sense, yes. But a research method never dies. It just waits for a new researcher to apply it. You’re worried about teaching sampling, correct?” Step 9: Hypothesis-Testing | Chapter | Core Topic

Kothari's framework for classifying research is a staple of these presentations. They provide a clear breakdown, often with comparative tables or side-by-side bullet points, making it easy to distinguish between different approaches:

Concerned with qualitative phenomena, i.e., phenomena relating to or involving quality or kind (e.g., investigating human behavior, motives, and desires). Conceptual vs. Empirical
