Research provides new domain of knowledge, new theories and laws, solution to a problem and open new area of thought. Further, it has the potential to question and analyses the existing theories in accordance to the present circumstances. Hence, it is important for educational/professional academicians to be acquainted with the process of research i.e. research methodology. It is worth mentioning that research is a systematic process and the knowledge of research methodology helps to understand what to do in specific situation. Research Methodology is a way to systematically solve the research problem. A researcher must know the rationale for using specific methods or techniques and establish their relevance. Methodology may be understood as a science of studying how research is done scientifically. A research work must act as a catalyst for further researches to be undertaken in the said field. In the recent past, many new dimensions of research have emerged catering to the vast changes taking place in the present-day social situation. The quality of research depends on the understanding of the research problem, the research methodology and the appropriate tools used for the analysis. Research Methodology is the central and most crucial component, element of any research endeavour in social sciences. Any researcher has to be well-equipped and must have command over this tool. The course Material on Research Methodology is designed to impart knowledge for scientific research to integrate qualitative and quantitative approaches in research and orient the researchers to techniques for precise, rational and scientific research. It is particularly meant for those who are engaged in survey research and have some basic knowledge of data processing, analysis and interpretation. The present text is a brief endeavor to explain the concepts of research and the various methods, tools and techniques for carrying out research in a rural scenario. The main focus of the book lies in the fact that it tries to explain the otherwise complicated terms such as research, statistics, probability and ethics in the most lucid manner with a lot of case studies to facilitate the user in understanding the same with quite an ease. The book is a designed as a textbook to cater to the requirements of the first course on Management Decision Systems to the undergraduate students of Bachelors of Business Administration course. The book is organized into 5 Units that provide a comprehensive coverage of all the relevant topics using simple and easy to understand language. “Learning by Doing” is one of the best ways to understand a concept and get to know it. Keeping the same in mind, the book provides a number of Case studies and to-do-activities to supplement the text and enable the reader to explore on his own as well. References at the end of chapters and self- learning questions will surely kindle the minds of the readers. I thank the contributors: Dr S Prasanna Devi, Professor and Head of the Department of Computer Science and Engineering at SRM Institute of Science and Technology, Vadapalani Campus, Chennai and Dr Meenakshi S Arya, Professor of Computer Science at SRM Institute of Science and Technology, Vadapalani Campus, Chennai to this book for their outstanding insights. Also, I would like to thank MGNCRE Team members for extending their extreme support in completing this text book.
