Statistical Methods in Medical Research

Null hypothesis (Ho) is the cardinal principle of equality in groups of objects or
subjects under study. It is the foundation of Statistical Science. The extent of
rejection of null hypothesis through statistical analysis validates our research or
inference about group of subjects, objects, or standard operating procedures (SOPs)
under study.

Statistical analysis plays a vital role in material science, business analysis, sports,
management, and biomedical research. A variety of books are available on statistical
analysis for students of mathematics, commerce, and management, but not a single
book is available for biomedical researchers and basic medical scientists who have
not studied mathematics at undergraduate level. I express my gratitude to Dr. Pranab
Dey, Professor, Department of Cytology, PGIMER, Chandigarh, for encouraging
me to write this book for biomedical researchers and basic medical scientists.

This book has been written with a focus on the requirements of students of
various specialties of medical science, basic medical scientists, and health workers.
Problems with solutions have been illustrated under various chapters for comprehensive
understanding of the statistical methods and their applications. I am of the
definite view that this book would meet the requirements of students of medicine and
basic medical sciences. I adore the pioneers in the subject whose theories and
methods have been cited in this book and dedicate the book to the galaxy of pioneers.
