Kothari advises researchers to verify the reliability, suitability, and adequacy of secondary data sources (e.g., government reports, journals, historical records) before use.
Kothari defines research as “a scientific and systematic search for pertinent information on a specific topic.” He emphasizes that research is not mere data collection but an original contribution to existing knowledge. He classifies research into four types:

Kothari dedicates significant attention to research design—the conceptual structure within which research is conducted. He distinguishes between:
He stresses that a good design minimizes bias and maximizes reliability of evidence. This taxonomy helps researchers choose the right approach
The true test of a Kothari PPT is not in studying it, but in using it to defend your research. Here is how the slides directly protect you during a viva voce (oral exam):
A well-structured PPT acts as a visual anchor, proving you have followed the scientific method strictly as prescribed by Kothari. He stresses that a good design minimizes bias

C.R. Kothari (Chaudhary Ramji Kothari) was a renowned Indian author and academician. His book “Research Methodology” is widely used in Indian universities and beyond. It’s known for its clarity, step-by-step approach, and extensive use of examples, tables, and diagrams — making it perfect for slide-based learning.
C.R. Kothari’s Research Methodology: Methods and Techniques is widely regarded as a foundational textbook for students and researchers in social sciences, management, commerce, and economics. First published in the late 20th century, the book demystifies the complex process of conducting systematic research. Its step-by-step approach—from defining a problem to writing a report—has made it an indispensable guide in Indian universities and beyond. Unlike purely theoretical texts, Kothari blends philosophical understanding with practical statistical tools, making research accessible to beginners.
