Biostatistics has become an essential discipline in modern biological, medical, and environmental sciences. It provides the statistical tools and methods required to collect, analyze, interpret, and present biological data in a meaningful way. With the rapid growth of research in fields such as biotechnology, microbiology, medicine, ecology, and public health, the ability to apply statistical principles has become indispensable for students and researchers.

This book, “Biostatistics: Principles and Applications” has been prepared to provide a clear and systematic understanding of fundamental statistical concepts used in biological sciences. The content is designed especially for undergraduate students of Biology, Biotechnology, Microbiology, Environmental Science, and related life science disciplines. The language has been kept simple and explanatory so that students without a strong mathematical background can easily understand the statistical concepts.

The book covers the fundamental principles of biostatistics including data collection, classification, measures of central tendency, and measures of dispersion, probability distributions, and statistical hypothesis testing. Emphasis has been placed on practical applications of statistical methods in biological and medical research.

Each chapter presents theoretical explanations along with examples relevant to biological studies. The aim is to help students understand not only the mathematical concepts but also their application in real-life scientific investigations.

It is hoped that this book will serve as a useful resource for students, teachers, and researchers interested in the application of statistical methods in life sciences.
