This book contains pertinent information on a different topic of Research Methodology, collected from different sources, including the course materials provided by the ICMR-NIE for this course. All the chapter have 40 multiple choice questions (MCQs) – MCQs with sr. no. 1 to 10 are of cycle 1 of BCBR; MCQs with sr. no. 11 to 20 are of cycle 2 of BCBR; MCQs with sr. no. 21 to 30 are of cycle 3 of BCBR; and MCQs with sr. no. 31 to 40 are of cycle 4 of BCBR. The answers of all MCQs are given at the end of each chapter (answers of MCQs of cycle 4 are provisional answers). I hope this book may helpful to all the candidates to obtain the knowledge of Research Methodology and hence, successful completion of the course.
